printing issues with model

M92 X3200.00 Y3200.00 Z3200.00 E873.00 ; set steps per mm

Those are some high steps per mm. What kind of a printer is this? Provide some more details please?

Results of M122? And M122 B1 etc if you have expansions.
Also send M98 P"config.g" to check for any syntax errors.

Have the heaters been PID tuned?
Extruder calibrated?

Its a cartesian printer its about 800mmx800mm. it has a nema 23 0.9 degree for the all axis because its all metal and i wasn't able to get it to move faster than 20mm/s with nema 17 which were 1.8 degree. I'm not sure if the steps per mm/ are correct but I used prusa steps per mm calculator and that's what got. as for the heaters, i haven't done a PID tune yet. I did calibrate the extruder.

The unterminated string error is because you're missing the closing quote "

PID tuning might help with the banding actually. thermal expansion of the bed or heater flex could be part of it. Same for the hotend.

Is it a lead screw based axis?

aprz

yes its dual lead screw for y-axis and single lead screw for the x-axis. im using two motors for the y-axis and single motor for the x-axis. as for the bed heater, i haven't connected it so that's not working now. what do you mean by heater flex?

Why is H1 commented out?

Phaedrux

Basically bang-bang can make it move up and down a small amount.

it's the bed, but not connected

aprz

@Phaedrux oh i see, so should i leave it as bang or change it to PID.

Phaedrux

Well once you PID tune it and save the results it will use PID once those results are loaded again. So you don't have to change anything in config.g

M303 T0 S200 will tune the hotend associated with tool0

Normally the bed is heater0 and tools come after.

@Phaedrux ok thanks ill give it try and see if that helps.

aprz

I tried auto tuning and it gives me an Error:M303: remote auto tuning not implemented

Phaedrux

Ah yes you're using a tool board. Can't auto tune yet. If you can connect to the main board temporarily you can auto tune.

800mmx800mm

thats a big printer. is it bowden or direct drive?

aprz

@Veti its direct drive and going to enclose it to keep the temp consistent.

We recently identified some issues in synchronizing moment over CAN that affect some prints, and fixed them in the RRF 3.3beta. As you are using a tool board, I suggest you try the beta.

@dc42 ok will give it try, thanks for the help.
