There are 2 different pinouts in common use on the 6-pin connector on the stepper motor. The colours in your photos are correct for one of them. But it's best to check with a multimeter. If you don't have a multimeter, do the following test:
Disconnect the 4-pin motor connector from the Duet
Spin the motor shaft to feel that it moves easily
Take a short piece of wire and push it into the two pins at one end of the 4-pin motor connector (for example, red and blue in your photo) to short those two motor wires together. Then spin the motor shaft again, it should be much harder than before.
If instead you short the pins at the other end of the connector together (green and black in your photo), it should also be hard to spin the motor.
Shorting any other pair of pins together should not make it harder to spin the motor.
@jasonpgr said in Fans stopped workinf:
Where would I look for a fan fuse and what would it look like?
If it's the version 1.03/1.04 board there would be a blade fuse right by the fan connectors.
You can pull the SD card and check it on a PC. You can backup the files that way as well.
If you connect the duet to just USB power does anything light up?
Are there any scorch marks on the board?
Thank you both for your help so far. I'm able to manually home with both of your suggestions, and have found that the reason for the separate moves on the Z motors was due to the motors moving out of sync. Upon moving in the Z direction one motor moves ahead of the other, causing the X gantry to come down on one side; then the other motor follows. Below is a quick photo of my printer. Do you think my issue is because of the Z motors being placed in different positions, or could it still be a configuration issue?
Thanks so much for helping me get this off the ground.
I figured it out! My Z leadscrew steps per mm were completely incorrect. The firmware was set for 5mm leadscrews & needed to be manually adjusted before uploading to the RAMPS board. Sorry for taking up your time. I appreciate your help though. Now on to configuring the BLTouch...
just a note..
If you solder on wire going to a screw connector the mechanical pressure will compress the solder overtime. and will eventually get loose..
better go with crimped and then solder (solder the wiren in the crimp) or pure wire
@dirtytwos said in Print not starting in center:
It shows that the printing is in progress, but when the print is about to start there is shake and pinch and the belt skips. After a fiew seconds it starts to print. But only at the left rear corner and not in the center.
You may need to reduce your accelerations for X and Y. On my corexy using makerslide, I have them set to 500. Also, make sure your belts are evenly tensioned.
In firmware 2.02 and earlier, axes 0 1 2 already exist and are called X Y Z. Each axis uses its own endstop number. When you use M584 to create a new axis, that will be axis #3 and it will use endstop #3 (the one labelled E0). If you create another axis, that will be axis #4 and it will use endstop #4 aka E1 endstop.
You can control the numbers allocated to your new axes by creating only one axis in each M584 command. If you create more than one axis in a single M584 command, the new axes will be processed in the order UVWABC.
Looks like you will need to power it from 5V, which you can get from the expansion connector or from the PanelDue connector. You can feed the output directly into an endstop input of your rev. 1.04 Duet.
