Spindle Stops after using Speed Ovveride command #53
Comments
Works ok for me with ioSender and a STM32F756 board. Which board map are you using and is laser mode enabled? |
I am using an ESP32-DevKitC-32D with the SourceRabbit 4-Axis CNC motherboard. SourceRabbit 4-Axis CNC motherboard works totally fine with the Grbl_ESP32. I changed to GrblHAL in order to check the backlash compensation. |
It seems the pin assignments for the spindle is wrong, this is the official mapping (?) vs the grblHAL mapping. Can you try with fixing the grblHAL map? |
Hello, happy new year ! Indeed, the pins are wrong. The correct pins can be found here Correction: The speed (RPM) override stops the spindle and NOT the feedrate overrides I earlier managed to implement the backlash compensation to our Grbl _ESP32 fork (https://github.com/SourceRabbit/GRBL_ESP32) so I really do not need to use GrblHAL at the moment. In case you can take a look at the bug I will be happy to test it. |
Hello, I'm using GRBLHAL with ioSender and it's been great, I recommend it to anyone who needs great performance. Case I need help with the map of pins I'm available to adjust you. |
I am not able to replicate this with a upcoming release, tested with ioSender, UGS and the SourceRabbit map on a bare dev board. |
Spindle is PWM, no laser enabled. |
I just found out that the Spindle Stops in the middle of the gcode cycle after I use speed override commands.
Tested it with the following control software:
