Thanks Jason. Appreciated. I do. It’s a good app for things like battery firmware updating, but when it comes to battery charge numbers it has to just report whatever the battery says. It has no other way of knowing.

You can. You just need a compatible slot wall angle. If you get the specs of the Microjig bit (how deep a slot it cuts, how wide at the bottom of the slot and the angle of the cutting blades) then you can get any bit that can cut that slot with a shaft size that fits the collet you have. You can sometimes get 8mm collets to fit 1/4” routers (e.g. Makita) if that’s an issue.

Hi and thanks for the kind words. You are spot on. The time I could spend on the channel got seriously derailed for a while. Frustrating all round. I’ve pretty much sorted it out now so should be able to start putting out at least 1 video a month from next month and aim to do 2 a month from January. Hope you’ll find them interesting.

I ran the tests with the included 27mm hose because its an M class model and the Festool manual states that the volumetric flow monitoring is calibrated only for the supplied hose. So I ran the tests on the basis that that is the hose people would use it with. Interesting thought, though. The end of a 36mm hose is the same 57mm diameter, so it will fit the outlet. I’ll try running the tests with a 36mm hose attached and see what it does to the results.

@@roughcutprince Excellent! That's the setup I'm most curious about. Just yesterday I ran an air speed test between the 27mm & 36mm hose on my corded CT SYS. The difference was quite remarkable, going from 5.5 m/s up to 8.5 m/s. The vac's exhaust temp was also notably cooler, indicating it's running more effeciently. I do not yet have a CTC, but your test could be the determining factor!

That’s pretty much the choice you’re faced with if you want to use Festool clamps in these slots - modify the slots or modify the clamps. I choose to leave the clamps as they are and adapt the slots. Just a shame Microjig made us choose. It would have been so much better if they had designed the system to be compatible in the first place.

@@roughcutprince Wouldn't make sense to have other clamps fit their system otherwise they are just selling a router bit and a idea. I bought my Festool style rail clamps from Ali Express @£6each so I had no qualms taking my Powerfile to them.

Hi in much the same way. The settings on the combination squares are the same. just use any long enough piece of material, scrap, etc. to make the settings then place each square with the ruler end on the floor and mark up using the lower edge of the square body as your guide. That way the markings are in the same position as before.

Glad it was helpful!

Unfortunately the height and profile of the clamps and the keyhole router bit are completely different.

@@roughcutprince That is what we call imperial measurements problem. Because I have perfect keyhole router bit in metric measurements, that fits with Festool clamp. And that's because Festool is EU based company of course.

@@casteliero now that’s very interesting. Mine doesn’t let the clamps fit. Do you have a name or part number of the bit you use ? I’d like to check it out.

My thoughts exactly: this way you can stay in the Festool/Bessey universe and can be certain that the clamp/slot interface has a defined force/surface area that ensures very little wear and yet secure parts safely. Konical mating surfaces need to be matching precisely and using a t-slot clamp in a conical groove can always be only a short-term hack as the groove will wear out/deform rather quickly.

Yeah, you could but the whole point was I didn’t want to do that and didn’t see why I should have to. So I made the microjig slots more compatible instead. Each to their own, I suppose. As the saying goes, you do you and I’ll do me.

The runtime is not just dependent on how long it takes the machine to deplete the batteries, but also on how long it takes to recharge depleted batteries. Have enough batteries available and runtime is limitless. But that’s likely not practical for most. The documentation says how long it takes to recharge empty batteries and it lies if the batteries are freshly depleted. It also doesn’t say that when the charger says a battery is back to 100% it also lies. So if you’re expecting the Festool documents to tell you everything you want to know, you’re going to wind up disappointed. Do your due diligence by referring to real world reviewers that have taken the time to find out the truth, you’ll be informed instead. So to inform is the point of the review. If you found the review helpful, as may have, it’s done its job well, as it did. If you didn’t find the review helpful, that’s fine too. I watch many reviews that don’t particularly help me. That’s the nature of reviews generally, RUclips or not.

Hi Keith. I've had no issues with the extractor and when I did need to change a bag, it was way cleaner than my old Bosch as the Festool is an M class with a bag and the Bosch is an L class with no bag. Battery life hasn't hit me too badly as most of the time I'm doing stop-start and not continuous. Occasionally I have to wait for the 2nd set of batteries to finish charging, and it would be nice if I could use bigger batteries, but it's never really slowed me down too much as I just switch to something else for a few minutes and get back to it. Overall still very pleased and glad I bought it. Hope that helps.

@@roughcutprince Great stuff.Think ill bite the bullet and go with the festool.Not a huge difference in the prices im getting but Festool cover theft under the warranty which is peace of mind.Appreciate the reply 👍

Hi. Yes it is a t-slot. It is a UJK Cam lock hold down clamp from Axminster tools.

You are missing the point entirely. If the app says 0% or 100% it should mean it. It really doesn’t matter why it’s wrong, it just is.

I’m actually thinking I’ll do a video of how to cut through a 94mm piece with a DF500. I’ll have to supplement it, but I’ll get it done. Keep an eye iut for it.

Hi Joseph The reason I moved up from the 8 degree was the chance that plywood might prove too weak long term. I haven’t had any issues so far, as the workpiece supports the slot and the likelihood of the clamp being repeatedly in the same place is pretty much nil. With your material, as you say, the 10 degree wouldn’t be any help. The difference between 8 and 9 won’t be huge, so if you have some spare bits of your material you’d probably be best trying cuts at 10, 11 and 12mm depth and see which is the lowest depth you can use, whichever bit you decide on. I’d start at the 10mm cut end and check after each one until you’re happy and then use the cut you choose as a depth gauge for future setting up. That’s assuming your material is at least 19mm thick. Let me know how you end up.

@@roughcutprince thank you, Sir. I’ll give it a shot

Metric time was proposed over 200 years ago, so it’s been around for a while. You can even get it as an app from your fave app store.

Can you let us know the part number? because I’ve seen no such thing

I noticed there was a difference in batteries when you took them from the ctlc vacuumcleaner; one was hotter than the other. (the charger started charging that battery later than the other) That could be an indication the hot battery has a higher internal resistance. (but perhaps there is a drift in the temperature sensor) If there is a load on a pack with a higher internal resistance that one with the higher resistance will drop in voltage faster under load. (and show emptier than the other, since the level of charge of these batteries is directly determined by the voltage of the pack). The higher resistance version will also be full quicker; but with these type of batteries, they don't charge from 0-100 percent at the same speed; till each cell reaches around 4.2V, they will receive full current from the charger (6Ah) and after they reached 4.2V per cell, the current will be reduced till they don't take any current. it's called CC/CV charging (constant current/constant voltage). For that reason the first 80% will be done the quickest. It's too bad that the app doesn't show the 80% status. But my guess is they call 4.1V per cell 100%, which in reality is not.. Charging the packs to 100% and store them that will will negatively affect their capacity btw. They are best stored at around 60% when not in use, the batteries will last longer.

Hi. Yeah, it is the one area Festool haven’t improved. I have used the Bosch for the last 3 years and it had been good, but as I mentioned in my CTC SYS review video, I found the Bosch wasn’t really designed for fine dust like brick or MDF dust as it was only an L class and had no bag for the drum. The filter got especially caked and was really messy to clean. The Festool is much better in that respect and as that was my no. 1 issue, I find I now only use the Bosch for general cleanup of non-fine dust. If only the Festool could take the 5.2 ah batteries, but it can’t.

Thanks Andy. Glad it helped. Now I understand the products better, I'm really pleased with them.

Hi andaval Some more than others, but yes. It used to be only traditional computers that had firmware, but there are so many products now that have software/firmware aspects to them. Cars, watches, TV sets, cameras, tools and now even batteries. It is a way for manufacturers to fix certain aspects of their products after they are out in the field, rather than there being no practical way to fix issues later. I must admit I don't apply updates immediately they are published, in case they cause problems, but after they have been available for a week or two, any big problems with them should have been noticed and corrected and then I take the updates.

@hovermotion thanks

Hi Norman thanks. I’ll look into that

@carbb did the suction drop happen at the same time as it beeped twice?

@@roughcutprince I noticed it before the beep. Maybe I could have made it work for me but just felt like it was not good enough

Mind if I ask what job you were doin at the time?

@@WhangaFish I was prepping 2 holes in drywall for my electrician to run wiring for an EV charger a customer of mine was having us install. So cutting connected to my osc tool and doing a very small cleanup.

Hi Mathew. Yeah, shame about the 5.2s. Thanks for the heads-up re the Metabo unit. I hadn't come across that one before, only 3rd party no-name Amazon specials that often have safety questions leveled at them. I'll check it out.

Hi Igor - I totally agree

The run time is the biggest weakness, but 6 minutes is really short. I'm curious - were you using 3.1 ah batteries or 4 ah?

@@roughcutprince i was using the 4ah. I had to buy the impact set to get the batteries. Which by the way also sucks. Makita makes better vacs and impacts.

@@ElDrKaiser The cordless Makita vacuums are awesome, we get about 45 minutes of run time with the twin battery system. And that’s actual heavy use.

@ryane are those m-class?

@@roughcutprince I looked on Makita‘s website and at least for the US website they don’t seem to share this info. These are the two models we’ve been using regularly at work sites.. XCV21ZX GCV04ZUX (this model is easily as powerful as some of our corded festool vacuums)

Hi Mathew. Yes, I know some have done that, but I didn't want to adjust any of the clamps to fit any of the slots. I just reasoned the slots should cope anyway and they didn't, so I decided to fix how the slots were cut. But hey, whatever works for you is right for you.

Hi. I'm just putting together a video on battery life, coming out this week.

I can no other answer make but thanks and thanks and ever thanks 😁

Hi Alexey. How long the Festool bags last is one of the things I'm monitoring as I use the extractor day to day, so I don't have a definitive answer for that just yet. But yes, it's one of the CTMC-SYS aspects that I need to keep an eye on and I'll likely do a follow-up video on how I get on. If I'm in the workshop, I'll use the Nilfisk or the CTM MIDI, so the CTMC SYS (as the Bosch before it) doesn't have to take the larger volumes of dust coming from bigger machines. Rather, it gets used either in the house or outside where the mains units are too awkward to take and the tasks there tends to generate fine dust (like sanding), but not vast amounts of it. As portability is one of my main needs for the cordless extractor, I didn't even consider the larger Festool cordless units so I did know the smaller bags were something I would have to deal with. With the Bosch I found that although the cleaning of the bottom drum could be mitigated to some extent by encasing the drum in a large bag before emptying it, I had no such luck with the main filter. It gets absolutely caked in dust and tapping it against a hard surface while it is inside a bag dislodged very little dust. The pleats just clung onto the dust until I cleaned them out with a small brush. That sent the dust everywhere, meaning I do it outside. Windy days just made it worse. Replacing the main filter each time would be far more expensive than changing a filter bag and because the Bosch is an L class only, there is no warning to tell you that air movement is impeded by the filter being clogged, so I had to do it each time and just accept that it was a very messy job that I really didn't want to do. That's why I decided I wanted M class and a filter bag. Maybe I leave the Bosch too long between emptying, meaning the filter gets clogged more often. Don't get me wroung, I'm not getting rid of the Bosch, it will just be relegated to general cleanup jobs that don't include fine wood dust.

@@roughcutprince I have a tip for you. You can use a bigger vacuum to clean a smaller one. First dump main dust from the container. Then inside a Bosch dust container shake a filter while having bigger vacuum on. Your Nilfisk should have enough power to leave no dust behind. I do the same with Karcher and it is quite safe to do. Or just bang some tree with the filter outside. It works fine. No need to brush it (with brush you are making it more prone to hold dust, it is actually printed in some similar filter manual)

I love the corded version..3 quid a bag, just put it on the price like

How does it work with the ctva preseparator. I have this separator and it’s great with midi vac

@@jrichardson6 the pre-separator does reduce airflow as all pre-separators and cyclones do, so the stronger the suction of the extractor the better. As the pre-separator has a 50mm port to connect to the extractor, you would need a 50mm to 35mm adapter to attach the provided CTC-SYS hose and the inner diameter of the CTC-SYS hose is also only 25mm, reducing the pre-separator air path from a surface area of around 20 square cm to around 5 square cm. So all in all, the dust extraction will suffer noticeably and I expect the result will be disappointing and not up to the standard of the MIDI and pre-separator. It may even trigger a low airflow warning from the M version of the CTC-SYS. Personally, I haven't tried the pre-separator with the CTC-SYS as, apart from the reduced performance, it would impact the CTC-SYS portability too much for me.

Hi and thanks for sharing your rationale. Really appreciated. I absolutely get where you are coming from and the challenges you face. The reason I wanted to develop the solution to better align with my personal circumstances was because I could see the potential of the MATCHFIT system. If not, I wouldn't have tried to "improve" on it - I would have just relegated it to a more niche role. Have you seen my follow up video ? It's at ruclips.net/video/T5jPeXPSsQU/видео.html if not. The reason I ask is that I was also wishing to try a lower cut depth and a cutter near to 14 degrees and achieved it. I ended up using a 10 degree cutter ( www.axminstertools.com/axcaliber-dovetail-cutter-d-12-7mm-x-20-96mm-k-8-leigh-no-80-8-s-8mm-952405 ) but found I could use your guide to set the cut depth. It gave me slots cut to 9.6mm depth, so no deeper than those cut using the 14-degree cutter. The slots as cut with the 10-degree cutter are a little snug for the Festool clamps, but the plywood I cut the slots into allowed me to very easily and quickly adjust them and I ended up with the best of both worlds - the right depth of cut and Festool clamp compatibility. I get that you are not able to second guess what other manufacturers do with their products, but many people do have alternative clamps and would find the MATCHFIT solution even more beneficial if it worked with those clamps. Certainly I'm very happy with my end result and have had no issues - probably because the top slot is supported by the material being clamped. But of course I only have to please me, although I am happy to share my findings with anyone who might find it helpful, including yourselves. But it is up to each person to decide for themselves if it is suitable for their circumstances, as I am not guaranteeing the solution, only offering the possibility. Again thanks for your feedback. I do like and continue to use the MATCHFIT system, just with a 10 degree cutter as it suits me better.

Please do - sounds an interesting idea.

@@roughcutprince And?

Hi. I haven’t heard if Michael has managed to try his idea as yet.

Have you managed to do this way? 😂 Im Just to curious

@@stefibs Sorry, major surgery, recovery, and (luckily) tons of work flow have dropped this tweak down the todo list for me. Why not take up the flag and let us know --- :-) If you already have the bit and clamps, it won't take more than a few minutes.

Thanks Michael! welcome to the channel. I must admit, the reduced thickness was playing on my mind as well, which is why I pursued the other cutters.

@@roughcutprince I'm revving my engine to make an integrated set of graduated on site work platforms and benches that will work together as a lego set. How many, which ones, and how the components are deployed will pend the scope and type of work to be done. Components will be connectable to one another both vertically and horizontally, including both side by side and end-,joined. All will have 20 mm hole grid (I bought Parf system tool), some with additional T-slot extrusions, and some with your version of modified Matchfit slots. The interchangeability you achieved in your experiments solves my problem exactly, as I don't believe it is possible for a T-slot extrusion to be designed to capture the Festool/Bessey clamps and leave even as much as 1/4" of 3/4" material in tact. Thank you again for the time and effort you put in to share your discoveries. I innovate a lot, but selfishly don't take time to post much.

Hi Ivan. Thanks. The update video is available now. It's at ruclips.net/video/T5jPeXPSsQU/видео.html

I only really thought about it when the latest electricity bill turned up alongside the news that the winter cap will be double last winter’s cap. Scary stuff for the December and March bills.

You're very welcome. It didn't take very long to ease the 10 degree slots at all.

Hi Glad you like the idea. Thanks. The follow up 10 degree video is up on the channel now under the title "Best way to fit Festool clamps in Microjig Matchfit dovetails". The direct link is ruclips.net/video/T5jPeXPSsQU/видео.html Have a look and let me know what you think.

Thanks Mark. I'll give that some thought.

Hi Robert. I'm working on doing just that. Just got to get a couple of items set up and I'll get back to you.

A few people have mentioned this, so I will get hold of one and test it.
