Just had a look and it definitely hits the trigger first, not sure why that isn’t stopping it as clearly the triggers are working. Also not sure why the z axis is homing upwards and not on the bed.by Zaly - Mendel90
Thank you - found the y axis and that one's working too. x_min:H y_min:H z_max:L Yes, homing the X axis is working, it moves towards then stops once its triggered the switch. The y axis isn't working though and the bed tries to move beyond it, and I had to turn off the printer to stop it.by Zaly - Mendel90
Just tried again to make sure and it did change to H x_min:H y_min:L z_max:L x_min:L y_min:L z_max:H I'm struggling to find the switch for the y axisby Zaly - Mendel90
Quotenophead They should change to H if they are pressed while M119 is typed. The switch should open and the input pulled high. >I didn't make any changes to the firmware, loaded it straight up from the USB. Not sure what you mean by that. It should have had firmware already installed and be ready to use. Did you load new firmware via USB using the Arduino IDE? If so where did you get it frby Zaly - Mendel90
Sorry for the late reply, had a family member taken into hospital so been all over the place! I've manually triggered the the limit switches and getting exactly the same when sending M119, >>> M119 SENDING:M119 x_min:L y_min:L z_max:L I didn't make any changes to the firmware, loaded it straight up from the USB.by Zaly - Mendel90
How would I find those values? I haven't been able to home the z axis as it tries to home above the frame, I think I may have already caused damage to the thread as it tried to home above the frame and then wouldn't respond to any commands to pause. I had to switch the printer of by the switch. I've just tried to home the y axis also and it tries to home the bed beyond the frame also so I thinkby Zaly - Mendel90
Quotenophead What position does M114 return? What does M119 show? M114 = >>> M114 SENDING:M114 X:0.00Y:0.00Z:0.00E:0.00 Count X:0.00Y:0.00Z:0.00 M119 = SENDING:M119 x_min:L y_min:L z_max:Lby Zaly - Mendel90
Thanks. It looks like x, y axis are correct. Still trying to troubleshoot the z axis. I can’t bring down the extruder head more than a few mm from the top even using the bar on Printrun. Same problem on both Mac and Windows OS. The firmware was working fine for the previous owner.by Zaly - Mendel90
So I now have Pronterface up and running and connected to the printer. I've uploaded a STL file sliced in Cura and tried to print but the print started with the extruder in mid air. I've double checked the x, y & z axis and they seem to be moving in the wrong direction when moved manually in Pronterface, any ideas? This printer had been set up and running on a Windows PC perfectly well, wouby Zaly - Mendel90
Thank you! I now have the temp working - but I don't have the temp bars as shown on your screenshot, it is working though. Just need to work out the next steps.by Zaly - Mendel90
I’ve just bought a second hand Mendel90 and feeling a little out of my depth. The printer was already constructed and had been used on a Windows PC. I’m trying to set it up on my IMac and struggling. I’ve installed Pronterface and it can move the printer extruder head and bed but it doesn’t have any temp control option etc. I’m not sure I’ve installed the firmware properly as I’m pretty unfamby Zaly - Mendel90
