Creality CR-10 Max - Connected but not printing

What is the problem?

I have connected OctoPrint to my Creality CR10 Max. I was able to send a G-code command to understand the firmware settings. Here it is.

I also get lots of connection status messages in the log.

I uploaded a gcode file to print. That seemed to work fine. But when I tried to print, it sat for a while and then both OctoPrint and the printer itself reported an error that it did not heat ("Error: Heating failed, system stopped! Heater_ID: bed - Printer halted. kill() called!").

What did you already try to solve it?

I reloaded the file and tried again.

Logs (octoprint.log, serial.log or output on terminal tab, browser error console ...)

Here is a bit more from the log.

Deas the bed heat up if you're just using the display menu without octoprint connected?
I guess there is something wrong with the bed heater. Maybe the cables aren't connected proberly.

The printer works perfectly when controlled directly.

Well then I think that's a case for detective @foosel :wink:

I fear I can't do anything here - it's the firmware that's reporting a heating error, that's completely outside of the control of OctoPrint.

I have also encountered a similar situation. I have CR-10S and Ender-3S .
There are two situations that can cause my printer CR-10S heating error...
fiirst, Only the usb line is connected, no power is turned on
second, loose power cord or poor power cord contact.
So, I think The cause of the heating failure is the power cord.

Thanks for the suggestions.

I have spent more time digging into this. I have sent the exact same commands that are executed locally - from the gcode file. I sent the heat commands.

M140 S50
M105
M190 S50

It changes the printer console to show 50 degrees but it never heats.

When I unplug the raspberry pi and manually set the temperature to 50 degrees it heats up fine. So there is no problem with the bed heating up.

I will connect Creality to see if there is a newer version of the firmware...

Any other ideas??

Thanks,
Dale

You could use a own marlin firmware
I also had some issues with the creality firmware and my own marlin with slightly modded example config solved them

I decided to return the printer.

I have spent too much time this far - roughly 25 prints. NONE of them have been good prints in terms of matching the design. I have measured and tried to calibrate with Cura. I installed my raspberry pi with OctoPi so that I could use OctoPrint. It was my hope that I could change some firmware settings, print and remotely monitor. But that failed - some kind of firmware problem. I looked at installing a different version of firmware, but heard about lots of problems doing that (including a convoluted way to get to actually update the firmware - remove screws, small hands...).

I think a $1k+ machine should be better than that.

12

Now the question is - what to buy that will start out printing to spec, and that I can upgrade to make it even better... Any suggestions??

I need a printer that is at least 300x300x?

Don't buy a Robo 3D. :laugh:
