Problem with tool change on coreXY pen plotter #288

Closed anbello closed 2 years ago

anbello commented 2 years ago

Describe the bug I have a coreXY pen plotter with grbl-coreXY 0.9i on Arduino nano and it is near all working OK with GRBL-Plotter. The problem is on multi group plotting and tool change. I have set to change the tool manual (Pause M0) but when a new group begin the pen goes up then appear the dialog box 'Tool change needed' and then immediately pen goes down. This last pen down should not happen and is a problem.

For pen up / down I have a servo controlled by 'M03 S50' for up and 'M03 S0' for down.

Please check this setting: I assume the PWM will be switched off via M5 with the result, that the pen goes down... image

OK, thanks a lot, if I remove the check the pen does not go down.

Is it OK to remove or maybe I should change in some way?

svenhb commented 2 years ago

Yes, sure it is ok to uncheck. It is for router with spindel, if you need to change the bit.
