Delta printer calibration with V1.0dev

kas

Hi Repetier,Spent two days trying to solve this problem, ...now completely lost :/ I just upgraded from .92 to 1.0.0dev version and recalibrated my delta printer using
https://www.repetier.com/documentation/repetier-firmware/z-probing/
- M321 S2
- G28
- G131
- M99 X0, M99 Y0, M99 Z0
- G132 S1
- M320 S2
- G32 S2Calibration is OK except the area opposite to A tower
in this zone, the extruder is 0.25mm over the plate
I tested my glass bed (D200mm) and it is not warped, so I shouldn't use G33
Is there a setting to raise/lower a specific region of the bed
Kindly let me know what I am doing wrong
TIA

Repetier

Most likely changing b or c angle will help here. But that alo has an effect on the other sectors, so be carefull. Normally only very small changes like 0.1-0.3are needed. G33 would also help here if you do not manage to optimize geometry further.

Thanks for your for your prompt response>> changing b or c angle will help hereJust to make sure, are you referring to Alpha A, Alpha B and Alpha C parameters ??Considering the specific area to trim, which angle should I try to adjust first ??You are doing a great job by the way :)

Repetier

Yes these angles I mean. Maybe think like having a circle with 3 bars below. If you move the bars one side of the bar goes up and the other down. But in the end it is try and error. Make a height map with repetier-host, store it as table over clipboard, change angles and repeat. You will see what changes in which direction and after a few iterations you hopefully have a better setting.

That did the trick, thanks :) My new setup:
Alpha A 210.500
Alpha B 329.500
Alpha C 90.500
This is my Delta printer calibration workflow:
- M322 S3 Reset auto level matrix permanently
- G33 R0 Delete distortion map
- G28 Home
- G131 Remove any extruder offset
- M99 X0,Y0,Z0 Adjust sliders using a stick
- G132 S1 Measure tower endstop offsets & stores
- M320 S2 Activate auto level permanently
- G32 S2 3 mesures, fix rotation of bed & store
- G33 S2 3 mesures, fix distorsion of bed & store
- M323 S1 P1 Enable distortion correction permanentlyIs there any missing commands ??
Is there any useless commands ??
Finally 'Z-probe speed' EEPROM setting seems to have no effect on G32 & G33 process (was OK with V0.92)Thanks again for your help
Is it possible to make donation using PayPal ??

For donation suse this link:
https://www.repetier.com/download-software/<br/><br/>Note that
- G131 Remove any extruder offset
- M99 X0,Y0,Z0 Adjust sliders using a stick
- G132 S1 Measure tower endstop offsets & stores
is normally only done once per printer unless you change endstops. No need to repeat this on recalibrations.

and didn't want to enter my cards details
I admit I was too lazy to read the whole text, but I may not have been the only oneOne suggestion: just add a PayPal logo to clear this matter

I've apparently got something wrong, because when I enter M99 followed by X0, Y0, or Z0, the motors remain locked and Repetier Host (V2.1.3) logs a "Unknown command:N72 M0". Not sure where the M0 is coming from. Also, I can run G132, but if I add S1, it ignores the command. Server 0.90.1 - PAN 56. Firmware 1.0.2. I just downloaded a fresh copy after going through the configuration tool. I set "EPROM set" to 1. I thought I remembered seeing it was supposed to be set to 0 to allow you to save, but 0 says, "eprom disabled" in the config tool.

Repetier

M99 does not contain a comma , just to be clear. It is you only use x0 or y0 or z0. That axis is then disabled for 10 seconds!

Culturedropout

No - I'm not using a comma. But if I type, "M99X0" nothing happens - all the motors stay energized. This used to work, so I'm not sure if there's an issue with the upgraded firmware, or what. Is there a parameter or a define that needs to be done to enable this feature?

Repetier

Please separate parameter with a space, not M99X0 but M99 X0.
