5 hours last night with the mm2001 and trying all the cutting programs and never got all things to work and finally nothing was working and all the motors were HOT. Today I am ordering a 1.4 board and drivers per this video so that It should be easier to follow and get things to work. I have a set of the smaller board and drivers for the original Arduino but I guess it will not work. It says it is for a 3d printer and since there are 4 axis I did not think it would work but you made it work so that is all I need to know. Items should be here Monday. Thanks for all your videos. I can't wait to get this to finally work after all these years! Thanks and stay safe. Don
Thanks again keith. I havent had any issues yet, but i will file this away for later. Sounds like, for how cheap they are, i should pickup a couple spare driver boards.
Thanks Keith, great knowledge, especially on stepper motors, nice sound and video editing as well. I'll revisit this when I connect up my Protoneer HAT (GRBL Micro Controller) to my Raspberry Pi CNC. I've also got some 2.8A NEMA 23's and TB6560 3A Drivers waiting to be used on a future version 2 of my home CNC. Earning a living has got in the way unfortunately, but appreciate your quality videos even so!
Hello rcKeith, thanks for all your informative videos on the foam cutting topic! They are very useful. Do you have a tip on how to straighten the hot wire before installing it between the spring? My spring pulls around 500g but I can still see a slight bend in the wire.
Hi keith, Thanks for the video link. I know my wire length is different, but I got a starting point. I tried to reply in your web, however, I cant open it at all this night. I have changed to weight system to pull the string. i read you used 700gram, I put twice the weight hoping it will pull the wire as its longer, however, after going horizontally as cutting tapered wing, the wire doesnt go back with good tension, as if the weight is not pulling it well, or may be its too heavy? and make too much pressure point with the bending at the pulley.
hello mr keith, you may not remember me but i used to write you about my project some time ago, thanks to you i could finally get the job done, then i used a variant called ugs to control the machine, i have bee using this machine to make foam mouldings with some success, i use a computer for each tower so i wont force the 8825 pololu driver drivers, but from time to time one motor tends to go the wrong direction damaging the entire work, it does it from time to time but now its getting worse and the machine is damaging a lot of material because it cuts the wrong way, i wonder if this has happened to your machine and if so, what could have cause this error, it changes direction in the middle of the cut, its happening ring now only in the right tower, the left one works just great, i use nema 23motor 1.8, thank you for ll the help you can provide me.
DRV8825 drivers should really only be used with NEMA17 at 2.0 amp maximum. NEMA23 are usually higher than 2.0amp. If you are trying to drive the NEMA23 with DRV8825 drivers then this will probably not work well and could be your problem.
Keith, at about 2 minutes 22 seconds into cutting foam, one of my stepper motors consistently shuts down. I have tried and inspected everything but cannot figure this out. Pleae advise.
Hi Johann. Not quite sure I understand your question but a lot the dialogue is still french even though you select the language on install or in the options. You can change some of them there is a language file in C:\Program Files (x86)\Jedicut\Lang. I've changed some for English but there is a lot built into the program that can't be changed. Time to brush up on your French😀
question:- whenever I click the UP button to jog both carriage, the vertical carriage moves in left, and the horizontal carriage in right move fwd. ? what is this issue, it both vertical carriage should move but it is not happening please help
Thanks Keith for taking the time to put this all together to help all of us. Thanks for all your videos.

Hi Don, new video should be out by the time you get the new hardware. Better firmware and software.
@@rckeith Thanks Keith, stay safe.
thanks very much Keith for spending time on this

Thanks for you kind comments. I'm slowly getting better sound . I've found it really hard to get good quality but hopefully I'm on the way

I've used the methods in this video a few times ruclips.net/video/gqsi9v6gkVk/видео.html worked well with a drill

An other question
Can i use an arduino uno whit stepper shield
Not with this firmware. DevCNC Foam supports the UNO with CNC Shield. www.devcad.com/eng/devcncfoam.asp
Hello Sir, do you have any pictures of how to plug the four limit switches to the arduino shield?
Have a look here on my website about halfway down the page there are some pictures rckeith.co.uk/grbl-hotwire-mega-5x-for-cnc-foam-cutters/
Thank you very much!
Keith, at about 2 minutes 22 seconds into cutting foam, one of my stepper motors consistently shuts down. I have tried and inspected everything but cannot figure this out. Pleae advise.
Try swapping the drivers to see if the problem moves to another stepper motor. Make sure you have the Vref set correctly
Hi can you tell why Jedicut allways get in French iinstalled it in German than I tried in English same

what is this issue, it both vertical carriage should move but it is not happening
please help
Can you confirm you are using the firmware from my website.
@@rckeith Yes I am using firmware shared by you, I had resolved my issue.
thank you so much for replying & for sharing this amazing project with us
@@nihalmankar4743 Glad you have it working
I tried switching to other mircostep drivers and the same thing continues, motor shuts off after about 2 min 25 seconds.
Have you set the vref for your drivers.
@@rckeith not yet but this is not a new machine. It was fine before. Where and how do I set it?
