I just came across your channel, and the amount of knowledge and effort in your videos is insane!! People need to know about this channel. Rooting for the next part!
Get a dial indicator (the "test" style will probably work best for this) and a holder for it to do precision rail alignment. A cheap Chinese one will do for this level of machine.
I tried to comment and ask about your grbl settings but it seems to have disappeared. 😅 What grbl settings will you use and how will you calculate the values? Specifically interested in your cartesian [X,Y,Z] steps/mm values at $100 $101 $102
I haven't done any tests to find the performance ceiling of the machine yet, instead I'm just using very conservative feeds and speeds. With regards to steps/mm, UGS has a great inbuilt tool to calibrate these values which I cover in the next video. These are my latest grbl settings: www.dropbox.com/scl/fi/hdi014467cphqdsoge14t/PXL_20240307_073643864.MP.jpg?rlkey=s622u2je3vkcr4iqzqk8i2cr6&dl=0 no idea why the steps/mm are such weird values all around 161 steps/mm (would expect 20 s/mm for 10mm leadscrew). 1/8th microstepping must be enabled by default on these drivers... Edit: indeed without any jumpers fitted to the cncshield TMC2209 drivers will do 1/8th microstepping! Smoother operation but less torque...
Yeah I think its auto spam removal magic. I'm keen to share the grbl settings I calculated for my machine if you interested. I don't know if they right and I'm still building the machine. It's a work in progress 😅

Hurry up with part 2
xD
Funny thing is that I wanna do something similar in UK

Got one, but the rails are so short it's hard to get enough measurements to ensure they are in fact parallel. Making a jig was far quicker and easier

I don't know why but youtube keeps deleting my responses. I think its because I added a link to my blog post with grbl settings.
Thank you for sharing your settings and I look forward to your next video of that inbuilt tool in UGS
@@mrcarlpaton Weird. It's not me deleting anything!

Wondering how might I put this tool to use? Look right here ua-cam.com/video/vSqf0CKwhuQ/v-deo.html
Cheap? No... no... RND is expensive 😅
Advice tho, preload your berring blocks 😊 * would need at minimum 1 more rail though.
