@droftarts Yeah its strange, still got to tweak the settings as im getting a very large seam still, but its not pausing now.

@droftarts Apparently if z hop speed is 0 that's what causes that pause. I changed that number and it changed that gcode line to actually have a speed so I think that's what was causing it.

I think I just forgot to add a number when I was setting up the profile.

Thanks for your help as I would of never spotted that in the gcode.

@droftarts That very helpful thank you. I will adjust those settings and I will try octoprint and see what happens.

Hi, the printer keeps pausing at the start of each layer and causes massive blobs on the z seam.

Hardware:

• Tractus T1250, 1m boden tube is around 1 metre long and it is old and I'm going to replace it. Hemera extruder.

• E3D v6 hot end.

• Duet2 v1.03

Firmware:

• RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.5.1 ELECTRONICS: Duet Ethernet 1.02 or later FIRMWARE_DATE: 2024-04-19 14:40:46

• Paneldue 1.21.3

I am not sure what is causing it, I thought it might be something to do with power loss recovery saving a reference point but I don't think I have that enabled in my config.

I thought it could be related to retraction but I have retract at layer change turned off and when the printer stops moving so does the extruder so I don't think it is that.

The minimum layer time is 0.1s. Retraction distance 5mm, speed 60

I also printed in vase mode and it worked fine, no blobs. But obviously, in vase mode, there is no stopping for each layer.

I have not turned on Pressure Advance.

No matter what speed I print at the printer will pause for the same amount of time, but on faster prints, the blob is much bigger.

I have attached pictures and a video. In the pictures it looks like it's under-extruding at the start of the layer and then by halfway around its back to normal.

So does anyone have any idea what could be causing it? I am probably missing something fairly obvious. Thanks

@droftarts Thank you for your reply, that's very helpful I will try changing the speed then.

This is the printer they have at work and when I joined a few other people had already tried to get it working with no luck. When I went to update it I forgot to save the original config, it was on version 1. something. But it wasn't really working then anyway, so my plan was to start again so I did the config from scratch.

I have also struggled to find any information about the printer, so that explains why then.

I've managed to get some prints from it now I rewired the hot end and added a new extruder but it's just the first layer and z offset causing issues now.

I will try the things you have said, thanks again for your help.

Hi, I can't get consistent trigger heights for my delta printer and it throws up constant errors when auto-calibrating and auto-bed levelling. It does not print a consistent first layer.

Printer: Tractus t1250 delta printer

Firmware:

• RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.5.1 ELECTRONICS: Duet Ethernet 1.02 or later FIRMWARE_DATE: 2024-04-19 14:40:46

• Paneldue 1.21.3

Hardware:

• Duet2 v1.03

• E3d v6 hot end, hemera boden extruder

I was following the calibration guide for delta printers and got to the auto-calibration step. When I got to the step to find the z-trigger height I could not get a consistent reading. I am not sure if this is hardware-related or software-related.

I have a range of measurements from -0.283mm to - 0.471mm. But each reading is different and a random number in this rang
e.

I am not sure what to do and what to check. So far I have:

• Tried doing it hot and cold and I got the same inconsistencies.

• Checked that the carriage wheels move freely.

• I am not sure how to check the motor current.

But it could be due to how the bed probe system is set up, I am not entirely sure how it works. It uses the nozzle so I assume it is a pressure sensor as it is a glass bed.

I am not sure how to check if this is working properly and what I would need to do to fix it. I have attached some pictures of the printer and the bed.

Is there anything I can do with the software to reduce this inconsistency? I am really stuck and not sure what to do.

Any help would be much appreciated. Thanks
