Just noting this here. When we make the limit stop switch change in Betas, we will need to update the offset routine to just home Z instead of leveling with the torque as in .77

Steven added a comment to T5283: Cold bootup, nozzle pushes into bed.

@jebba Quiver uses geared Z motors which hold the axis in place in most conditions. The Mini 2 is using standard motors which would drop axis more quickly without the break board. The shipping packaging would hold up the axis in shipping so the issue would largely be if the printer is transported after already assembled.

jebba added a comment to T5283: Cold bootup, nozzle pushes into bed.

I guess if there is a brake board on Mini2, why wouldn't one also be needed on Quiver? TBH, I'm not sure how it operates.

marcio added a comment to T5283: Cold bootup, nozzle pushes into bed.

Up in Z a tiny bit sounds like a good solution, as long as the tool head would stop at the top of the Z axis, in case it was resting at the top when it was turned off.

@brent.i: Not really. Because Marlin has no knowledge of a state for "both nozzles up", so basically the nozzles need to be in one state or the other. At startup, I have to force the nozzles into a known state.

I will investigate, but unfortunately there may not be a way to solve this problem. Even though the percentages range from 0 to 100, these values are stored in Marlin as 0 - 255. What you are likely seeing is rounding errors which cause the values to deviate +/-1. The only way to get an exact representation within show fan speed from 0 to 255, like Marlin does on the older LCD.

@marcio Thank you for the push, we will get this distributed for testing for customers. This one was originally reported on T4886 which was a TAZ 6 with HS+, and reducing the current fixed the issue. We will run more tests with the same printer and tool head combo in order to verify.

Wed, Jan 9, 8:46 AM · Marlin
marcio added a comment to T5137: Universal Tool Head Adapter: Tool-heads "Clicking".

In any event, I pushed FW .30 to lower the current on CecropiaSilk_SingleExtruderAeroV2, AchemonSphinx_SmallLayer, BandedTiger_HardenedSteel, DingyCutworm_HardenedSteelPlus to 960 mA, regardless of board. This should at least match the current on those toolheads would get on the Mini 2.

Wed, Jan 9, 8:43 AM · Marlin
marcio added a comment to T5137: Universal Tool Head Adapter: Tool-heads "Clicking".

The only thing I can think of is that certain of the toolheads have a half-height motor. Perhaps they do not operate well with 1250 mA. According to Tyler, the HS and HS+ use the larger motor so before making it any changes we have to determine whether the HS and HS+ are also affected.

marcio added a comment to T5137: Universal Tool Head Adapter: Tool-heads "Clicking".

The reason for this is that originally all toolheads used 1250 mA, but this is more than the EinsyRambo was able to provide without overheating, so the current was turned down for the Einsy. It seems peculiar that you guys are seeing clicking issues. Normally clicking indicates too little current, rather than too much...

I'm closing this out. I agree with @marcio that adding additional increments would add more clutter to the screen. I'm wary of the sensitivity of the touch screens to pull of the exponential increment. The cool down button fixes the requirement for getting to 0 quickly.

@marcio Ran another print on 2.0.0.67, the cooling fan turns on with T1 selected now, but doesn't seem to turn off. In the following gcode, the fan turned on to 100% and didn't turn off but remained on through the whole probing sequence.

G1 X299 Y23 F1000                         ; slow wipe
G1 X298 Z15 F2000                         ; raise extruder
M106 S255                                         ; turn on fan to blow away fuzzies
G4 S5                                                    ; wait 5 seconds
M107                                                   ; turn off fan
G0 X248 F1000                             ; move over to switch extruders
T0                                        ; switch to first extruder
M109 R{material_probe_temperature_0}      ; heat to probe temp
M204 S100                                 ; set accel for probing
G29                                       ; probe sequence (for auto-leveling)

I'm guessing this is because the workaround was for M106 not M107, I suppose this could be avoided by using M106 S0 to turn the fan off in the absence of further workarounds.

This is by design. Homing cannot set the Z precisely enough to limit travel beyond the bed, due to manufacturing variances. It is only after G29 that the true bed position would be known, but at that point the axis limits cannot be changed. This behavior isn't new. Every FW we've released up to now allows you to crash into the bed.

@alexei: The serial port on the Archim board is managed by the CPU, so if the code crashes, the serial port will go down. This is different from what happens on the Rambo/MiniRambos.

@mjwesterhof: Good catch. Since LULZBOT_ENHANCED_WIPE is always defined on line 1476, it looks like the consequence of this bug is that for all printers LULZBOT_WIPE_SEQUENCE_GCODE is redefined. The redefinition basically restores the old behavior in that there is no wait for the wipe temperature to be reached and also gets rid of the drop to probe temperature afterwards. Interesting.
