CoreXY axis don't move at printing

@phaedrux said in CoreXY axis don't move at printing:

And just to confirm, you can jog the axis motors around no problem? It's only when you start a print?
Have you tried a different gcode file to print?

Thats right. I can move the axis and home it and everything is fine until I want to print. Then it doesn't move.

@phaedrux said in CoreXY axis don't move at printing:

You can test by deleting the resurrect.g

Ok one moment I'll try it and give you some feedback

AimRabbit

OK I think I found the problem.
It was the ressurect.g.

But now I get this error I attached the M122 for better diagnostic.

I don't understand why the VIN is decreasing that much.

Phaedrux

What is your power supply?

Are the VIN terminals screwed down tightly?

PSU is 24V/15A
and yes I screwed it tight down.

Phaedrux

Have you tested the output of the PSU with a multimeter?

It could be failing. Do you have another 24v PSU to test with?

mrehorstdmd

Is there a T0 or T1 statement to select a tool somewhere in a config file or in the print gcode?

@mrehorstdmd Yeah there is one inserted by cura in the slicer start code.

If there wasn't the heater wouldn't heat.

I don't think so. I uploaded the gcode. It's in the first post as an attachment.

@Phaedrux I'll will check the VIN and give feedback in a few minutes

@phaedrux said in CoreXY axis don't move at printing:

Yeah you were right the VIN decreases from ~24V to ~10V.
Did you know a good PSU which I could buy? It seems that I have no luck with that printer.

I had to change nearly every piece exclude the frame

Phaedrux

I would recommend a Meanwell PSU. The wattage will depend on if you're powering a PCB bed heater as well, or if it's an SSR controlled AC mains heater.

mrehorstdmd

I second that. MeanWell makes good stuff. Avoid the cheapo "LED" power supplies that litter ebay. MeanWells cost just a few $ more and are far more reliable.

How can you tell junk from the good stuff? Look for certification marks like CE, UL, TUV, etc. The more of those it has, the better.

@mrehorstdmd said in CoreXY axis don't move at printing:

It also helps to buy from reputable distributors like mouser or digikey.

Here's the one I use. (canadian mouser store front) https://www.mouser.ca/ProductDetail/Mean-Well/SE-200-24/?qs=sGAEpiMZZMsPs3th5F8koBXG%2F88ctzcM7%252bcCQ8TI45g%3D

Ok. And yes I have a PCB bed heater connected to the duet.
What a PSU could you recomment for a Duet 2 Wifi, PanelDue 7i, E3D Chimera, PCB bed heater, one tool fan and two part fans. I realy appreciate your help. Thanks a lot!

Sorry but I'm from germany and it's very expensive to ship and tax. But thank you now I know what I'll looking for. Hopefully everything will work after that replacement.

Phaedrux

Well Mouser is just an example of a reputable distributor. You'd have to find something similar locally.

The PSU I linked is suitable for a printer without a PCB heated bed.

This link will help you calculate how big the PSU needs to be: https://duet3d.dozuki.com/Wiki/Choosing_the_power_supply

Your power supply voltage is probably dropping when the bed heater turns on. Is your bed heater definitely a 24V one; or if it is dual voltage, have you wired it for 24V not 12V?

Yes it drops at heating the bed. I asked you that in an other thread but you didn't answer I thought of this it doesn't matter.
Ok now I take a look at it but there are no hints if it's 12V or 24V. I can see that there are 3 points where you can wire it. I took 2 pictures for you.

dc42

Can you measure the resistance between the two wires? What size is the bed heater?

I measured 3 ohm and the size is 330x330mm.
