Just as an update for anyone that has had this issue and solved it, I replaced my heater block, nozzle, heat break, thermistor, and heater and still got the MAXTEMP hardware failure code on my first print. I even re-calibrated my Z-axis and redid the bed leveling, turned the fan on max even for the first layer. I am printing Build Series PLA at 215C with the bed at 60C. At this point I'm not sure what else to do.

Welp, turns out my Hot end was cracked in the heating element and the hot end just broke off inside the heating box. So done with this Pulse, trying to return.

@mpirringer I was using 0.4mm nozzle, PETG at 255C, with infill at 25mm/s, 1st layer at 10mm/s, and outisde perimeter at 15 mm/s. If i set my E-steps back down to the stock value I get really bad under extrusion but no more slipping. It seems that there is a mismatch in the gear ratio of the stepper motor and the BondTech that isn't being accounted for. I switch back to PLA and still having the same issue.

It is the stock BondTech extruder. I would set it to extrude 100mm and it would only push 40mm through. When printing, I would have to set the extruder multiplier all the way up to around 1.5 just to get a decent sized bead. Taking the hot end apart now to check if its clogged. I already went through and cleaned the nozzle out. The bondtech extruder clicks when extruding. I've messed with adjusting the tension screw but no luck there. And of course its a 3 week response time for Matterhackers support right now.

I went through and calibrated my Esteps and in order to get the correct extrusion length, I had to up my Esteps from 450 to 1117. It extrudes the right amount but now I have been having endless crashing issues with my Pulse XE. Do you think this has to do with it pushing the BonTech extruder to hard and its jamming?

I have been getting this error that past two times I have tried to print. This all started after I fixed my E-steps when I found out that my Pulse XE (D124) was under extruding by 60mm. I am printing a 20x20x20 cube and it stops on the second layer after the first half of the solid infill layer. I have only had this printer for less than a month and have yet to have success with it. I am printing PETG at 250C with the bed at 70C.
Extrusion Multiplier: 1
Fan Max 100%
Fan Min: 70%
Fan disabled for 1st layer
Initial Layer speed: 15mm/s
Infill: 25mm/s

UPDATE: I am now getting the Error:Heating Failed triggered, system stopped! Heater_ID: 0. Again after the firsst half of the second layer. Except now the printer moves to the right and does a few back and forth jerking motions and then grinds to a stop and the error pops up. When i try to cancel the print, it just errors out in place and can't be controlled. At my wits end with this thing.

2nd UPDATE: I reset my Printer and recalibrated the Z-axis. I am no longer getting the temp error. I have a new issue now. About halfway through the print, the nozzle moves to the far back right of the printer bed and continues printing. Did I somehow mess up my firmware when I adjusted my E-steps?

Turns out my printer (Pulse XE) was under extruding by 60mm. Checking to see if this was the issue.

This is with PETG on a Pulse XE. Can anyone help diagnose the issue I am having with the top solid layers? I lowered the speed all the way down to 10 mm/s and have 4 top layers with 15% infill but still having this issue

I am new to 3D printing so I have pretty much been sticking with mattercontrol for slicing and such. However I have noticed that the "expand thin walls" functionality doesn't really work most of the time. Instead of replacing thin sections, it just skips over them leaving voids in the model. Is this just a display bug or is Matterslice really just neglecting those areas instead of replacing them with an appropriate thickness layer?

@mpirringer Would you mind sharing your begin, end, before layer change, and after layer change gcodes that you use in Prusaslicer? I am having issues getting the z offset working right. I use the G29 command to do the bed leveling but afterwards the nozzle is well above the bed with just the standard GCode. And it doesn’t seem like the nozzle is moving up between layers

@mpirringer Thank you for taking the time to help out. I will post an update once I work through the steps.

@cdk

I am having issues printing smaller sections of parts. You can see in the photos below that for larger sections of prints, it is fairly smooth, however for the small sections (i think these are called "islands") it gums up. I am very new to 3D printing so please excuse any wrong terms. Does this have anything to do with the retraction settings?

FYSA, I have a Pulse XE, I was printing Ryno at 240 C with a bed temp of 73 C

I also noticed that when I scaled down my 3D model, it caused issues in slicing for both programs. specifically in merging parts. Any idea why the slicing fails when scaling down?

@mpirringer PrusaSlicer works perfectly, thank you! That solved my issue.

Should there be the other two programs available? I am running into issues getting my .stl files to slice properly so I wanted to try the other engines. There are often large gaps in the generated preview regardless of what model I am trying to print.
