Fantastic layman's explanation of ABS and INC, another good use if you have both sets of measurements on a drawing is to cross check between both. If your working using INC, before say drilling a hole is to do a quick check in ABS to make sure the measurements coincide.
I agree 100%. The greater confidence I have in the accuracy of my DRO the more I will use it. I've used blocks to calibrate mine but do not have the confidence in myself that I am as accurate as I should be.
Good point, I was able to borrow some stick mics, and over 600 mm the DRO was out by 1.2 mm on my newly fitted linear scales, there is a scaling parameter to correct this. I think there was also an incremental scaling parameter, ref every 50mm or so.
I know my dro is out as I've checked it and tried to recalibrate it, but using the manual it refuses to go into the recalibration mode. I've followed it about ten times at different times and still the same result. In the same way my dro will not allow you to reset a zero when in imperial. I have to switch into metric reset to the dimension I want ( let's say diameter of the work) then go back into imperial if I'm working that way. It's bloody annoying. I'm seriously thinking of replacing the DRO unit for a better one despite the extra cost as long as it will work with the glass scales, even if I have to rewire the plug to get it to work.
Got my first dro , sino, the Chinese manuel sucks and I'm not a wizard but not stupid either so I'll be watching your videos over and over. I appreciate the time you've taken and you explain very clearly. THANKS FROM OHIO.
I watched about half of this, then went back to watch This Old Tony's video on DRO's. Came back here and I have to say a much clearer explanation of whats going on. I look forward to seeing you covering off more on DRO's as I think that there is far more you can do with them than people suspect. I'm in the happy, or unfortunate position of of having 3 machines with DRO's on them, all 3 being different manufacturers. I need to get my head around the old Heidenhain system on my new to me mill, still to be set in position.
Excellent video Jon. Very well presented. My DRO came with a very thin instruction book, most of which I didn't understand. I learned mostly from videos like yours. Was a while before I understood ASB INC. I also use the DRO to find centres and PCD. More videos on the DRO would be very useful Jon. Cheers Nobby
Great video Jon, I’d like to see more videos on this subject if possible. I’ve been considering putting dro equipment on my machines and some basic knowledge on them will be invaluable
I left a similar comment with Joe Pie: please get yourself a lav mic. they don't cost much, but they will make your voice sound so much better than the in-camera mic across the room
Hi Jon. Extremely well explained and simplified for the complete DRO novice to understand, or someone who has never written or read a working drawing before. Reminds me of a box where only the internal dimension were given,lol. Cheers Tony
Absolutely wonderful, as an novice, I have never understood it that way, thank you for this. I have a Chinese (SINO) on my mill, that I can't understand the bolt hole circle functioning and setup. Can't wait for a video about that ! Thank you for this !!!
Well explained Jon . Only my big mill has a dro at this stage . Yes , some drawings can get overloaded with construction lines & dimensions esp as we were never allowed to dimension inside a part on a drawing . A lot has seemed to change on drawings since the standards we were taught in the late 70's & early 80's . 👍
Hi Jon. I must admit i have never used the inc function. Must get my head round it. I have used the circle function quite a lot. What would we do without the DRO. Imagine how hard & long winded it was for engineers back in Dick's days with play in the machine. Great video. Steve.
Hi Steve, thanks for the comment. I learnt without DRO so it never leaves you. I feel sorry for those who have never not used a DRO, as when they break down, there's a steep learning curve ahead. Cheers, Jon
Thank you. I get it now. Probably not use it as explained just yet. I use the 2 functions as if it was 2 DROs at the same time. So can pick up a different datum for two operations on the same piece. Ang on - is that what you just explained......
I hope my Sammie was paying close attention and making notes, because with chemo brain fog, I will have to come back when the fog has left the pond 😁. Great demo Jon, and clear as a bell. I sure miss being out in my shop, but hopefully will be soon, Besr
Excellent synopsis on dimensions, im guessing many hobbyists never have the chance to view or work with professional engineering drawings, surprisingly, each detail draughtsperson can be quite different as you no doubt know. An art form when done well. Thanks for sharing.
Hi John, 100%. Those that have not quite grasped proper use of dotted lines have caught me with my pants down before....... Long story lol. Cheers, Jon
@@jonsworkshop Yep, been confused by dotted lines, and drawings that were in both 1st hand and 3rd hand projection, maybe an idea for a video?, I still have to think when looking at drawings now, used to be automatic, even though reading title block beforehand for view, scale, dimensions etc. A great help now is most 2D GA's and detail drawings are generated from 3D models, so there's a small ortho model shown, or several, plus sections on complex or high end components. Best regards John
Well Jon, That made... sorry what where you on about I was licking my windows n not paying attention! Actually what I meant was, I went to the workshop and made all the parts shown in your tutorial HONEST 😁 As always Dude stay safe n well. TFS, GB :)
Very helpful video Jon. I would love to see more DRO function videos. Those of us who own import DRO’s know the manuals that come with them are not clearly worded on how or when to use the many functions. SDM for example, is one mine has but I have no idea how to use it. More videos on this subject would go a long way to help get full use out of the many functions available.
Great video. I’ve never understood absolute vs. incremental. I have to admit I’m still a little fuzzy on the how and why, but I’ll figure it out with your help. I’ll watch the video until I get it. Thanks again.
Jon this is excellent subject material. I get confused when using my DRO also. Therefore, I try to keep it in ABS mode. I would like to use my Inc more than I do. There is a function where you can preset the dimensions using Inc and just dial to ZERO on each dimension. I would love to see more about Inc and any other functions of the DRO. Bolt circle function finding different angles etc. I am all about learning new things so you can bet I will be here waiting for the next videos. Thanks for bringing us along
Great video and very helpful. I've used a few of the features on my DRO such as the hole circle and sub-datum points but it was a bit of a struggle figuring them out. The manuals are so poor. Looking forward to more.
Great Jon! You did it for us! Thank you so much, but I challenge you to read my dro instructions and even understand anything as it's in Chinglish! You've made me understand the differences between the two styles of measurement. I did (and taught in fact ) Technical drawing to 'A' level standard but absolute measurements were the norm back in the days of laying parts out on the surface table using a vernier height gauge. Long before electronic measurements were even thought of lol And yes I would love to see videos on different functions especially the hole circle pattern and SDM. Ps the name samrodian is all one word derived from my three Christian names all rolled into one and pronounced as you would if taking to someone. Me lol
THANK YOU, yes I know I'm yelling but I appreciate what you just explained here. If you get a chance I would really like to see how multiple Datum points (SDM) would be setup and used. I installed a DRO on my mill a few months back, I'm a home/hobby machinist if you could call me that and this helps a lot. I am also wanting to learn the hole pattern function and I imagine different DRO's may use a different way of inputting to get the same results but I'm not sure maybe they all use the same and try to keep it universal.
Thanks for a great explanation of that DRO function. I have a much better grasp on how they co-relate now. You are an awesome teacher, you can "dumb down" stuff that's technical for us mere mortals!...LOL. Cheers from Canada
Thanks Jon, good instructional video. One problem I have with the Sino DRO on my mill is setting up angles using the DRO, eg setting a vice or fixture to a precise angle using it. The instruction books Chinglish description of how to do it is driving me insane.
I thought Pattern Maker's new a thing or two but I gaining more respect for Machines ( i through they got on a lathe turned the dials ) Kit from down under
Interesting video Jon, it will help many, won't help me as i only have a poormans dro, with one function, absolute🤣🤣🤣🤣, but having said that, being brought up in an era with no dro's i normally stick to old school dials, which suffices the work i do, I doubt if i will ever spend to have a proper dro, unless one drops off a christmas tree🤣🤣🤣🤣 Thanks for sharing see you next time👍👍👍👍👍👍 regards Kev
Hi Kev, thanks for the comment. Yup, I learnt the hard way too, I sometimes still refer to the dials as a sanity check even though I have the DRO. Cheers, Jon
Great video Jon, now I understand the difference between ABS and INC👍 are you able to tell me how to input a diameter on the lathe DRO so the part diameter decreases as I remove Meterial? Thanks John
Thanks John, would you believe it, I have never used a lathe with a DRO lol. My guess is, turn a Dia, measure it, go to calculator function and type in what you measured, then press the X0 button. Don't forget to press the calculator button again after to return to ABS mode. Cheers, Jon
with incremental you would need to be realy carefull when zeroing the dro at least if its done the way you shown on the whiteboard realy interesting way of showing how it works , havent seen it done that way yet even though there are a few explanation videos about the use of the different options on a dro , having a set of these on a single channel would be helpfull having the different options explaned (the way you did with the piece of cardboard) in seperate videos would save me some time scrolling through a video explaning everything halfway without showing the drawing with the refferences on the workpiece (that realy helps) the most clear explanation ive seen before yours is from blondihacks
I wish I had time to watch this but 23 minutes is just too long. I would love to see a vid that explained that in 5 mins. Its probably a brilliant vid.

Good instruction Jon, it may be worth doing a follow-up on calibrating these DRO,s using gauge blocks
I agree 100%. The greater confidence I have in the accuracy of my DRO the more I will use it. I've used blocks to calibrate mine but do not have the confidence in myself that I am as accurate as I should be.

Morning Jon. Thank you for the clear overview of DRO ABS and INC functions. Please continue to make videos which show other useful DRO functions. 👏👏👍😎
Will do Andrew. Thank you.
Thanks Jon. Helpful indeed.

@@jonsworkshop Thanks Jon I’ll give it a go.
of special interest is the recover function when power is lost and the hand wheels have been moved while the power is off.
angle function would be great, I've read the instructions numerous times and i'm still lost😁
Noted Paul, on the to do list
basically you can use incrementals inside the absolute or along side :)
with incremental you would need to be realy carefull when zeroing the dro at least if its done the way you shown on the whiteboard
realy interesting way of showing how it works , havent seen it done that way yet
even though there are a few explanation videos about the use of the different options on a dro , having a set of these on a single channel would be helpfull
having the different options explaned (the way you did with the piece of cardboard) in seperate videos would save me some time scrolling through a video explaning everything halfway without showing the drawing with the refferences on the workpiece (that realy helps)
the most clear explanation ive seen before yours is from blondihacks
