Thanks dc42, that makes sense now

@totalitarian said in M203 Printing Max Speed:

@dragonn I already have it in there, but it's set too 200mm/s (nice speed for homing), I don't want to print at that speed though.

Z hop moves are short, so it won't get up to anything like full speed because of the acceleration limit. What makes you think that the Z hop is too fast?

On my delta I normally use 0.3mm of Z hop, with the Z speed configured at 250mm/sec and acceleration 2000mm/sec^2.

@totalitarian, I don't know how play in the arms looks like in prints. But I suspect it would not leave nice patterns. Who knows, deltas are complex machines.

It's easy to check for play of the ball joints, just wiggle the arms, any click-clock sounds are bad. Rumour says that if you have play in those small joints you can gently squeeze them on the edge in a vice or with some pliers to increase the preload.

Thanks dc42, got it working in the end

M400; Wait for current moves to finish
M915 P3 S2 F0 R0; set stall detection threshold
M913 E90; reduce the motor current
M83; relative extrude
G1 S1 E500 F3000; fast extrude
M400; wait for current moves to finish
M913 E100; restore motor current
G1 E20 F300 ; extrude slowly 20mm of filament

The board is mounted upside down, nothing below the board except my desk. Strange one indeed.

Correct, E0 not E1. If your Duet is under warranty, please ask your supplier to repair or replace it.

@ioiiooo said in Trying to avoid running levelling before every print:

If I put G29 S1 in my config.g, do I still need to run it before each print as well or will the mesh stay in memory between prints?

It stays in memory, unless you cancel it with M562 or G29 S2.

Were you definitely printing from the SD card on the Duet at the time?

The min/max is over the period since you previously ran M122, or since power up if you haven't run M122 before

Got it, had to put M570 S999 in the config rather than execute it via the console.

Thanks all

@totalitarian said in Trouble powering part cooling fan:

I think that is the way I have to go. Always on for the hotend fan and fan 1 for part cooling

Either that, or get the blown fan mosfets replaced.
