Hello, and sorry for this question but I need an explanation with the "jog incremental VS distance VS percentage" first some details, my machine is a custom milling machine that I retrofit. Ball screw 1605/5mm pitch servo motor HBS57 2.2N controler HBS57SH setup with 3600 pulse/rev Ramps 1.4 Arduino mega with MEGA 5X firmware in. Using Openbuild Control Software last version. and I'm workoing on a MacPro M2. after all this, my question is simple, how can I set the jog functionality to give the value I want Jog increments is set by default to 10mm increments. I want it to move 10mm. Moving the cursor percentage if I put 100% the stepper motor staled Cursor at 50% give me of course a movement of 5mm cursor at 1% give a movement of 9.9mm I cannot get how to have a real 10mm movement If one can explain to me how I can change, set up or just understand how it works. Please note results are the same for setting 100mm 0,1 increments Thanks a lot for your help
The slider only controls jog speed. If the motor stalls, you have the max rate or acceleration set too fast. If you have your speed and acceleration settings tuned and the axis properly calibrated, a 10mm jog will move 10mm regardless of the jog speed slider setting. Have a look here for how to tune these: Configuring Grbl v0.9 Since you still have an issue at 50% speed, it sounds like you need to significantly reduce your current speed / acceleration settings to start with (try 25% of your current values or less). Once the machine is working reliably, you can then tweak these settings back up again to find the values that start to give problems, then back them off by ~20% to give settings that are reliable.
Thanks a lot all for your replies I will have a look on the acceleration as this is the setting I didn't chnage until now
