That looks really odd to me. Can you post a couple of pictures of the printer? Preferably with the effector as close to X0Y0Z1 as you can get without damaging anything, and then one or two different photo angles at X0Y185Z1.

Thanks!

Hi Danal,

Yes I did fit Haydn mag arms length 440.47 mm

Thanks

Hi Danal,

These are commented out in the home file for Delta Calibration as per the documentation they are not always commented just at the point of posting.

Thanks

Thanks, excellent stuff, I will take a look at all of that.

Just to triple confirm: The running file on the printer is going to end with the carriages (approximately) 5mm below the endstop switches, correct?

Carlo

@Danal

Hi Danal,

That's what it's supposed to do but I cant confirm as it homes to the below error so it doesn't bounce.
It used to do as intended but I rolled the firmware back redid the configs via the online tool since these errors.
Note* the height Z-50 is myself trying to move the effector after homing.

Not sure this helps.

Thanks I know its a lot to scan through it is appreciated.

We will get it going. I appreciate your patience in re-posting stuff for the "new guy" looking into this.

@Carlo Your active high endstops are incorrect, should be M574 X2 Y2 Z2 S1 ; Set active high endstops.
It also looks like you have both RR3 and RR2 configs in your config.g ? file

Good catch! Though you mean 'high end' endstops, as in their position on the printer; the S parameter is for active high/low (describes how the microswitch works).

yes correct, which version of the firmware is being used? as it's confusing

Carlo

Great stuff homing now works and endstops offsets now look... correct also
Quick calibrate returns:
M665

Thank you!

Hi Ian,

M115
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05 ELECTRONICS: Duet Ethernet 1.02 or later FIRMWARE_DATE: 2019-12-13b1

If that still needed.

Thanks

boldnuts

@Carlo can we see your start gcode from your slicer?, you using G32 (calibrate) before printing?, maybe G29 S1 to load the bed mesh?

Carlo

@boldnuts
I have no start code yet having failed to get a layer down yet didn't want to add any complications,
However I have been doing G92 Z0 with paper G32 before attempting aprint ..I never home after probe and always with heated bed and nozzle, bed @ 70c nozzle @ 220c.
I have done the mesh but don't use it .. more to know it's flat..ish I think?? height maps are above in previous post.

If that help ?

Thanks

boldnuts

You need to run G32 in your start gcode before every print and it might be a good idea to run G29 to load the bed mesh as well, then recall it with G29 S1

Danal

@boldnuts said in Another Predator:

YES!

This is one of the big keys to running a delta. Let it find the bed, every time.

Carlo

@boldnuts

I'll try the mesh I do G32 before every print attempt.
dc42 commented a well built delta doesn't need bed mesh so not wanted to ..because I want a well built delta printer

Thanks

Carlo

@Danal @boldnuts
This is the height map it just finished ...is it ok?

Thanks
