P3P + Snapmaker A350 + Enclosure - Calibration Settings

Hi folks,

I am stuck trying to get a proper calibration run out of my SM A350 with enclosure. Due to the enclosure, I have placed the P3P outside and passed the longest bowden tube (that came together with P3P) in order to reach the SM Print head.

Under Loading Offset, I have entered: 1193mm

Under bowden tube length, I have entered: 110cm

It splices ok, but when it comes to loading the filament, it stops midway, and the next step is to feed the filament into the extruder.

I cannot for the life of me figure out what is wrong? I have tried removing the printer profile from the P3P, added 50cm to make LO 1593mm and 160cm for the bowden but it is still only pushing it half.

Am I doing something wrong?

Hi @moccajava, thank you for posting here.

The LO value does not have to account for the Palette outgoing tube length of 110cm. On Palette’s menu if you go to Printers > Select printer > Edit calibration data, the outgoing tube should be set to 110cm so that after the initial splices are complete, there should be a small amount of filament coming out of the tube.

This printer looks to use its own bowden tube/extruder to driver filament to the hot end. With this in mind, the LO should include the length of the bowden extruder (starting from the top of the tube clip), the bowden tube provided with the printer, and then the length of the hot end.

Do you observe if the temperature on the printer changes during the smartloading sequence? This could be a reason why the movement stops halfway. We’ll do what we can to look into this further.

Hi Adalyn,

The printer does not have a bowden extruder. The usual method is to place filament in, and let the gear feed/load into the hotend.

That being said, i did notice p3p heating up the nozzle to 200 when i initiated print from p3p.

But how do i get p3p to feed further, since it stops around the midway mark of the longtest tube (currently set at 110cm).

Hi @moccajava, if the filament is not feeding any further to reach the end of the tube it could be an ingoing drive issue. Are you able to use Controls > Drive to see if any of the inputs have trouble loading/retracting? Also, when it stops loading halfway through the tube, what does it say on Palette's screen?

Hi,

I have captured the screen in original post. See “Feed extruder” screenshot.

Adalyn, to add on. There is no drive issue since I was able to clear the filaments when I had to abort the loading process midway.
