Printer prints at constand slow speed no matter what I adjust

@bayvan it's probably the gcode that limiting. Post the first part of a gcode file up to the start of movement

@bayvan said in Printer prints at constand slow speed no matter what I adjust:

But from there including bed mesh and printing something is capping the speed to 40mm.

including travels?

Share your other files like homing and bed.g.

Do you have a start.g file?

Where are you seeing 40mm/s for the speed?

bayvan

@Phaedrux When homing and bed leveling, including travel, everything is ok. On bed mesh and printing, everything is slow. I printed a test without bed mesh. Homing and bed level is again working as it should. When printing starts, everything is slow, including travel movement. Speed is reported in the Duet Web Control readout.

@bayvan The last thing in your bed.g file is G28 Z. This will home just the Z axis by calling the macro homez.g. Can you post the contents of homez.g - maybe there is something in that file which is capping the speeds. Also, can you post the contents of config-override.g if you use it - just in case there is something in there which is limiting print speed.

droftarts

@bayvan The code you posted shows a speed of F3600, which is 3600mm/minute, or 50 60mm/second.

On a CoreXY, diagonal moves (ie ones that use only one motor) are limited to 1/1.414 of the speed set, so a move commanded at 50 60mm/s will run at ~~35.36~~ 42.43mm/s.

This is because CoreXY machines are capable of higher speeds in X and Y directions than 45deg diagonal moves, because both motors contribute to pure X or pure Y motion, whereas just one motor is used to perform diagonal motion. RepRapFirmware makes use of this to maximise performance. So on a CoreXY machine, in RRF the maximum XY speeds and accelerations can be set to 1.4 times the 'normal' X and Y values.

also make sure acceleration control is off in your slicer

@droftarts said in Printer prints at constand slow speed no matter what I adjust:

.............@bayvan The code you posted shows a speed of F3600, which is 3600mm/minute, or 50mm/second.

The last time I looked, there were 60 seconds in a minute and 3600/60 came out at 60 not 50. Either way, if the OP is to be believed, he stated that homing moves are normal but printing moves in DWC are showing 40 mm/sec, so something else is capping the speed like an erroneous M203 or M220 for example.

Thanks, edited. Also makes more sense for the speed he's seeing, perhaps.

@deckingman Thank you. It was a single line of code in homez.g. I feel so stupid. This is my 3rd printer, and they all use Duet hardware I should've seen that. Thank you all for the help.

Don't feel stupid - we all make mistakes from time to time. Out of curiosity, what was the offending line?

bayvan

@deckingman I deleted it, and I don't recall the exact values, but it was M203 that was capping the speed.

@bayvan can't say that never happened to me (-:
