The power supply was bad and would not read more than 3v we put a diffrent one but it only gave 10.4 so we know it is the power supply thank you got your help

not sure what it could be we have traced all the wires and we used the wires as directed in the manual. We have also unhooked all of the wires on the RAMBO to make sure its nothing else that has been hooked up

Dig around in Configuration.h for the motor current settings and post them please. (must be from the firmware that you loaded on to the printer!)

line 701 i thtink this is what you want. (155,155,155,165,0)

Glad to hear it.

Yes that is correct. PC Networking and Hardware repair

It is all set up and when we turn on the power the orange light and the green light flash and everything goes dead. Have tested a new power supply and a new Rambo nothing changes

Disconnect the bowden tube from the hot end (leave the push fit connector screwed in!) and try to push filament through the hot end by hand while it's at temperature. It shouldn't be very difficult to do. If it feeds ok by hand, try extruding filament from MC while the bowden is disconnected and ...

It's concerning that the motor is mis-behaving while connected to the extruder drive channel, but not when connected to a normal axis channel. Has anyone messed with the firmware for that machine? How long has it been in service? tnx. g. The firmware has not been touched on either of the two ...

That's an impressive stable of printers if you've got 10 Max's. Would love to see a picture. But onto helping you. Have you tried changing the motor current for the extruder motor? Perhaps set it to match the axis motors, since those drivers move it. I will test this and see if I can figure out how ...

I have 2 rostock max v2 the motor for the filament extruder is not moving it just clicks. I have rewired 3 times and it works if i switch with one of the axis but will not work while pluged in where it should be. please need help asap.

I have 8 built and working properly.

Try re-running the EEPROM_CLEAR program and then reload the firmware.

Let us know if that works.

Thank you this fixed the problem

we are in the max rambo.

tnx.

tested each switch in order x,y,z

Double check that you've got the right axis wired to each of the right connectors. Also make sure that you're connected to the xyz MAX connectors and not the minimum endstops. It is on the end stops and they are all on the correct axis. When i send the M119 command it shows an H after the correct ...

When they are not pressed it will show a L after the axis letter and while pressed it shows an H like it says it should. All of the wires are in the proper places and plugged into the proper port on the MotherBoard

I sent the M119 command on every axis and they are all correct. When i send the all command using Matter control it goes up hits the switch and just keeps smashing into the top never stops and when i turn it off all of the end stops are being pressed.
