@fcwilt It’s not true, we are trying to solve a problem that seems easier than what it really is on a complex and not so well documented machine. You gave a really big help trying to figure out what the problem is, and giving option on how to solve it.

By the way if you want to build one I can give you the cad files so you have the machine too and we can complete the build of a well documented and easy to work scara arm.

The problem is fixed, G92 command was in a bad position, it was such a simple solution...., sorry to have bothered you so much.

@JoergS5 thanks for the help, you fixed it. I moved the G92 command position and now it works as it should, it was such a dumb fix..... I am so stupid.

@JoergS5 , so endstops works, the leds on the mobo turn on when the machine reaches the endstop in the correct position and if I interrupt the homing sequence before trying to home z the dashboard gives me x,y homed. What I am not able to do is home Z, my z endstop in an FSR switch that triggers when the nozzle touches the bed. My hotend in the home position is outside the build plate, to home Z I need to move the nozzle to the bed center, that is my 0,0 position, to do so I wanted to use a G0/G1 move, but the command continues to move the arm without stopping. This is a post with the video of the machine behaviour.

Something curious that is happening is that if in my homing file I do not home z, and in the dashboard I use a g92 command to home z, the arm works in the right way, but if I add the same command inside the homing file it does not work.

@JoergS5 The endstops work correctly, I tried at the start of the homing file to set G92 Z0 but the arm still does not work.

@JoergS5 sorry, I forgot to link the old thread, @Phaedrux told me to open a new one to make DC42 read it. So here’s the link there you can find also the video of the machine.
I tried not to use any parameter but the printer gives me an error, the arm cannot be moved because it’s not homed even if the arms have reached the endstops.

@Phaedrux yeah I imagine but I am not in a hurry.

@Phaedrux I have created the recap post this is the link.

I’ve built a 5bar scara arm, I can home the 2 arms in the home5barscara.g but when I try to do a G0/G1 move to set the hotend position to the center to home z, the arms overshoot the required position. If I only home the arms then send a G92 Z## from the dashboard the arm works as expected.

This is the config.g file: config (1).g
This is the homig file: home5barscara (2).g

Thanks in advance for the help.

@Phaedrux said in 5bar scara Problem configuring z probe using fsr switch:

This thread is a bit long now. Can you create a summary post of the issue as it is currently and I can pass it along to DC42 to see if he has any suggestions.

@Phaedrux do you have any news from DC42?

@fcwilt yes, it would be simpler to link them there
