What slicer are you using?

What are the settings for the first layer (height, speed, etc.)?

Frederick

@Sindarius sure!

@jens55 yes, M561, post amended.

G1 H1 X-335 Y-335 F1800 ; move quickly to X or Y endstop and stop there (first pass)G1 H1 X-335 ; home X axisG1 H1 Y-335 ; home Y axisG1 X5 Y5 F6000 ; go back a few mmG1 H1 X-335 F360 ; move slowly to X axis endstop once more (second pass)G1 H1 Y-335 ; then move slowly to Y axis endstop

Thanks for that! When I do that, the carriage moves towards the "b" motor, not the "A" motor. I would gladly move the switches back to where I currently call 300,300 to match yours if it would be easier.

Thanks!

@jens55 prints not fully finishing. Not sure about the moves thing

Hello,

If any additional information needed for the requested above. Please let me know, I would be glad to provide.

@wdenker sorry, I was looking at your config.g you posted earlier, and I could have sworn it said the extruder drive was on 0.0 and the filament sensor was on 1.out1.in!

Could you post your current config.g, in case anything has changed?

Ian

@Dr_Ju_Ju said in CoreXY mode not being honored:

M584 E1.0 ; set drive mapping E (extruder on 3HC)

I figured it out for the movements.. Now to figure out the filament sensor. I can't have 0.1 assigned to two different axis'

@dc42 and Jay_s_uk

Thanks for the tips. I was able to get the QGL working properly.

One other question, I would like to include a test to see if the probe is already attached to the hot end. I believe that "if sensors.probes[0].value[0] == 0" is the right command for that but I don't know what to add after that to tell the system not to deploy the probe again just use it as it already attached.

Thanks again for the help.

@deckingman

Thanks for the feedback

@Terradive

Mesh Bed Compensation can cope with a bed out of level but you are better off trying to get the bed as level as possible which reduces the work Mesh Bed Compensation needs to do.

There is the link to the documentation that discussed manual bed leveling:

Manual Bed Leveling

Read it over and ask any question that may arise.

Only one of my printers uses Automatic Bed Leveling. Here is a link to a quick-and-dirty video Automatic Bed Levelinglink text

My other 4 printers just have thumbscrews.

Solved: the solution is using the inmutable bit on the file

I am very thankful I found this thread because I was having the very same issue and, after some experimenting with your scripts it works better for me too now.

However, I do have a question: why there is no M915 command on these routines? I assume if ignored it assumes a certain value lie S3??

I mean, I tried with and without M915 and it works, so... I am confused, somehow

@MJLew
i can try ur gcode just to see how it print , but as i see features are not added any wehere so far?
also what i noticed with my models, cylindrical is ok when i used prusa slicer but 2 tower with hole in it still seams terrible

@fcwilt I see, strange that I never noticed this before, thanks for the clarification

@jens55 said in PETG as a support interface layer for PLA:

e using for print speed for your separation layer and also what you are using for support density? Also, do you use normal printing temperatures for the PETG or do you print the separation layer at a nozzle temperature different from a normal PETG prin

I use a raised temperature of 260°C for the PETG and a regular 225°C for the PLA. The interface print speed is at 60mm/s. Z-Top distance is set to zero. Support density is set to 2.5mm Top interface spacing is set to 0.00 Bridge print speed set to 40mm/s

@jens55 said in PETG as a support interface layer for PLA:

I believe Cura allows for a variable density where support density is low but then goes very dense just prior to the separation layer. I could not find anything like that in PS.

Yes, this is unique to Cura, and generally crashes (at least for me) when I try to use it on more complex parts.

I generally find printing PETG at higher temperatures helps drastically. Also make sure the nozzle is clean as PETg loves to stick to itself.
If you want, send over some pictures as there might be some other aspects causing the failiures

I will add a 2 cents comments here: never underestimate the Z axis calibration, I had your problems before and was just a matter of calibration on my Z axis (Im a fan of 0.1 and below layers jaja).

Also I will vote a +10 on the overestrusion and here I have something I looked somehow deep: the teeths of the hobbed bolts on the extruders, even the teehts on the bondtech dual geared extruders can have a huge impact on extrusion, to a point where changing them to a smaller size can give you upto 4% difference on the extrusion rate. Even on diferente material you can find a difference: softer material suffer more on this that harder materials. And even speed changes extrusion sice teehts tend to "bite" more deeper if you print faster.

@deckingman you are a legend. Yes, that was it. Switched H0 to H1 and it's working now. Thank you 👍

Hello,

I think I don't need a hight torque.
Yes I use 6HC with toolboard 1LC, my firmware is 3.5.0-beta.4 .

I've just added D3 V0 on XY and Z, and sent a G32 for testing, the result is magnificent when the bed goes up but when it goes down the noise is the same because the speed is fast and I believe the spreadCycle is activate.
For X and Y too, I think I need to change the acceleration parameter.

Thanks

Edit: Ok, I left that idea aside, I see my printer's motors doesn't like it too much, when all I'm doing is moving the head at 1250mm/min.
I hear footsteps jumping.

@droftarts Thanks!
