Can you share a picture showing the failure?
Are you getting clean cuts before it fails?
Is Y axis the double axis on your machine?
I agree with you. This should be doing great at those settings. Especially 3mm DOC and 10mm/s.
My first question is how is it failing. The pic might have spme insights.
Some thing I would be most suspect of:
- Are the grub screws on the pulleys tight? Slipping on the motor shaft is a common issue
- Are the bits burning? Bits are a very important part of the machine. Finding a good 1/8" bit for starting is really helpful. They need to have the right geometry, be sharp, and be hardened for CNC. How many flutes do yours have?
- It could be an intermittent wiring issue. These are hard to debug. Running M122 after a failure could give you the ola olb feedback from the TMC drivers. Those flags are only right when the motors are engaged, and after a failure though.
If I can only do one thing, it is tell you that you’re not crazy. This should be working better than it is. Whatever is wrong will get fixed and you will be making a ton of projects soon. You don’t have to be an expert to get this to run, and it looks like you’re already being very detail oriented in your progress so far. You’ll get there.
