@dc42 Can the 5160 be used as an external stepper driver for the Duet Wifi 2?

@dc42 said in "Laser" Fried Duet?:

Are you sure is was the ground pin that you shorted the PWM pin to? It seems unlikely to me that such a short would damage the Duet.

I suggest you check whether the MCU is getting hot, and if it isn't then work through https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond in case the Duet can be recovered without replacing anything. Also check whether the WiFi module is getting hot and whether the SD card is OK.

MCU is worm. Esp worm, checking SD-card is good. This is how my lights are.
Also is does not show up when connected to the computer. The ESP does also not do its power up led blink.

I got the duet wifi. Thanks for helping out.

While fiddeling with the laser setup here:

I managed to short the pwm pin on the logic gate circut (this one) to the GND pin. And the Duet instantly just stopped working.

The extension connector still delivers +3.3 and +5. And the E3 pin also gives out high.

Do i need to get a new Duet or are there someone who knows wich components that i probably fried?

When in workplace coordinate system is it suppose to do the heightmap offsetting from the machine coordinates? And when setting up a 557, this also uses the machine cordinates. Is this a bug or am i missing something? Thanks for all help.

Hello
Im using my Workbee CNC to isolation mill some PCB. And i want to be able to use the mesh bed leveling to be able to cut 0.05 depth into the copper.

Im using v style engraving bits and they have different cut width dependent on the depth of the cut.

Im able to get mesh bed leveling to work like this:
Navigate over to my PCB. I set the right work coordinates for x,y,z.
Then i add the probe: M558 P4 C2 I1 H0.5 F60
The probe map that i need to make need to be set in machine cordinates. like this: M557 X130:170 Y126:166 S3
Then i run a G30 to reset the Z height for the machine cordinates.

Then i run the; G29 to run the map.

After all this is done i run the job from work cordinates. But i think the mesh bed leveling is offsetting the unused machine cordinates, and not the work coordinates.

Anyone have any tips on how to get this to work?
