@Charlie the 2504s are a good pick and they like to be driven at spec.

@Phaedrux I repeated the e step calibration 3 or 4 times so I feel pretty good about it.

I posted the same thing on another site and someone mentioned that retraction settings can cause this same issue. I double checked my settings and I had an override on my ABS settings that was still 2mm. I lowered it to .5 then tested it last night and the print looked perfect this morning. So the issue was my retraction setting surprisingly.

@Kiwi3D said in BL Touch . CR Touch:

M280 P0 S1000
M950 S0 C"121.io0.out" ; 121 is my toolboard CAN ID
M558 P9 C"121.io0.in" H5 F120 T6000

You can't use M280 (set servo position) before you define the pin with M950. For the proper sequence of GCodes, please refer to the Configuration section of the document Connecting a Z probe - BLTouch (which covers the CR Touch, too).

@Phaedrux

Nevermind, stupid me found the issue while posting up the codes. I've adjusted the F value but not the T value. It now does indeed work 🙄

@droftarts @dc42 :

I further checked the setup & realize that the PT1000 sensor is 30mm in length with 4mm diameter. But the Biqu extruder slot for hotend & sensor is of 15mm.
This means half the sensor is outside sensor slot & not in contact with hotend.

Shouldn't this affect the PID learning & heater behaviour?

Machine is a Voron Switchwire

@jay_s_uk didnt really showed up when searching for it, the pinned macros showed up but they are a bit bulky

@vbtalent2 you'll find the M307 details here
https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m307-set-or-report-heating-process-parameters

@Kiwi3D im core XY , , you are core Xz
but you should still be able to use my home x , you need to modify it for your core XZ

something like this

; homex.g echo "home the X axis" M400 ; make sure everything has stopped before we make changes G91 ; relative positioning M915 P0.0 S5 H200 F0 R0 ; Configure Stall Detection M906 X550 ; set homing motor current G1 F8000 G1 H1 X-350 ; Home X-Axis independently M906 X1000 ; set homing motor current M915 P0.0 S35 H500 F0 R1 ; Configure Stall Detection M400 ; make sure everything has stopped before we make changes G90 ; absolute positioning G1 F12000 X152.5

@abraxas please use code tags for posting code on the forum, it makes it much easier to follow and spot errors, and you won’t have to put in strange formatting. I have edited your post.

Ian

@oliof thank you again for your input.

I took belt A and B off completely off and tested the smoothness of each bearing/pulley as best as I could, fortunately they are all rotating smooth still. But yes, what you said makes sense.

to my surprise my gantry is wildly out of square to the point where when moving the Y axis there is much more resistance than the X axis. I will have it all squared/racked properly, I have a feeling (and hoping) that this is the cause of all the rippling in prints.

I will keep this post updated.

Kind regards,

Gordon

I think it will help a lot if you share your config.g and a few photos of your setup. So guys here can pinpoit the issue. Also if you use the search in the forum you will find similar trouble , together with the solutions.\By experience usualy the problem is the speed of comunication between Duet and the external drivers

@LuniLAB Can it be that your feedrates are a bit high?
Is it a delta? According to the square bed, i think not...
Can your printer reach this fast z-movement?

@jay_s_uk
OK I THINK I HAVE SOLVED IT THANK YOU, I HAVEN'T FOUND ANYTHING IN THE MANUAL THAT INDICATES YOUR SUGGESTION

I finally found the time to test and wanted to share my conclusions with you.

The vertical artifacts on the curves in the previous photos, were caused by some (Orca) slicer setting. Most probably the jerk is reduced too much somewhere (orca slicer changes jerk depending on line type). When using a Super Slicer, these artifacts are much less visible (constans jerk).

In my stuff I found 1.8 degree steppers. I decided to compare the prints with previous 0.9 degree steppers, the design of my printer allows me to change motors without changing belt tension. I prepared an object that requires line printing at 45 degrees to have clean information on each stepper. I present the results in the photos below:

And here I am very surprised, because both prints are almost identical and I can't tell which is better. I always thought that 1.8 motors were better.

On flat surfaces at some speeds you can clearly see the reflection of the belts. The arches and ends show artifacts with a smaller spacing than the belt. I understand that it is the superimposition of two effects, the reflection of the belt and the ringing?

@Derek-F probably best to start a new thread. Then we can tackle the subject of getting you upgraded to 3.5.2

@DonStauffer I went up to 9000, and it seems fine, and faster.

SOLVED - used conditional gcode to control print zone. Reverted back to sensor attached to heater source. This provides a more stable control for the heater.
The conditional gcode reads multiple zone sensors to determine the adjustment needed to drive the heater.
Thanks for reviewing the post.

@Phaedrux Thanks a lot, that has done the trick.
Changed value to 80%, now there is no error anymore when zLift is carried out.

Please mark topic as solved!

@droftarts said in Parsing error when loading height map:

@sbNielsen

You have changed the axis length from 1700mm to 17000mm, and 900mm to 9000mm?! Also, you only have 17 points for each line of the probe data; you need 18 to go to from 0 (the first point) to 1700 (the 18th and last point) in 100mm steps.

Ian

Damn it, I change things to quick and then I fuck it up, sorry!

It works now! The main issues was the missing 18th column in the grid..

I feel stupid and happy haha, thank you for your help and patience!
