Flashforge creator pro ---> Duet 2 wifi

Gubbfittan

I am trying to help a friend who have a Flashforge creator pro.
He started the convertion to a duetboard and then he gave it to me and here i am
The things that has been done to the machine is the following:

The rightside extruder has been removed and i did a quickfix and printed a part that acts endstop.
A BLTouch has been added
Extruder termocoupler has been removed and replaced with a thermistor instead.

Here is where the problem starts.
When i home each axis it goes well and also when i home all. But after homing all i get the following error message:
G28
Error: Failed to load height map from file 0:/sys/heightmap.csv: failed to read line from file

When i try to do a G32 the x-axis wont home, only Y axis, and it goes to far, with a rattling noise as a result.
After a few seconds it starts the bed leveling, and it goes what seems like random over the bed but only in the middle and left side and does 6 points and after that i get this message:
G32
Error: in file macro line 13 column 26: G30: expected number after 'S'

@Gubbfittan Please post your config.g, homeall.g, bed.g, and response to M115. Regarding the heightmap, I expect you just need to create a new one, but let's get the other things fixed first. If you want to post the current heightmap.csv too, I can have a look to see if there's an obvious error.

Also, can you make a diagram of your printer, showing where the endstops are, where X0 Y0 is, direction of travel for X and Y axis when positive movements are sent, size of the bed etc? Because it sounds like the endstops may be set to axis minimum positions, when they should be maximum.

Finally, test the endstops for correct operation: see https://docs.duet3d.com/en/How_to_guides/Commissioning#h-8-check-endstops

@droftarts
Thanks for a quick reply.
I will do what you requested in the order you asked, otherwise i will forget half of it

Regarding the heightmap i dont have a heightmap.csv
I tried to just create a file named "heightmap.csv" but that did not help anything.
My skills in paint is not good, but here it goes:

@Gubbfittan That looks like a bed.g file for a Delta printer, not a Cartesian machine. Generally, bed.g is used for levelling the bed plane with 3 points on Cartesian machines which have multiple independent motors on the Z axis (as you appear to have), or for using bed adjustment screws on machines with a single Z motor; see https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_auto_levelling

RepRapFirmware used to support Cartesian bed levelling using G30, but only supported up to 5 points, and has now been removed from the firmware, and bed mesh levelling is used instead.

The heightmap error may just be that there is no heightmap.

From your diagram, it looks like your endstops are set up correctly, so I think the error is the number of points you are probing in bed.g. Follow the instructions I linked above to create a new bed.g file.

@droftarts
Hi and sorry for late reply! I realy appreciate your help.
The machine only has one Z-motor.
Strange about the bed.g. It is supposed to be a config for this printer.
Anyhow,the printer only have one motor for Z and a BLTouch.
So i think the guide you refer to does not apply ?
Sorry if i ask dumb questions, English is not my native language.

If you only have a single motor you could do the manual leveling assistant which would tell you how much to adjust your bed screws to get it level. And/or use the mesh compensation to map out the surface of the bed and adjust on the fly during a print.
