https://www.3dhubs.com/talk/t/how-to-rescue-a-print-that-stopped-mid-way/2392 and https://www.instructables.com/id/continue-failed-3d-print/ have helped me in the past.

Here is where I am at now:

Phil looks pretty good, the grey one is the new one, the black one is the one from the factory. I am getting close. There is an issue with the hands on my version.

You can see the hands did not fuse together well, a little spaghetti.

Then I printed the calibration circle that comes with MatterControl.

The bottom was perfect!

The top not so much.

Then I did the finishing test and that turned out pretty good! Minor blobs (running too hot maybe) and the tip of the pyramid did not stick.

Next I dialed up retraction to 6mm and now hardly any stringing. I am using Matterhackers Ryno btw. Next I will deal with the blobs and I am noticing a bit of filament powder left behind the bondtech, so I might want to dial that back a bit.

The first thing I did was to calibrate the extruder length (link).

I now can spit out 100mm strips all day

This thread will document my journey to calibrating my Pulse XE after doing a hot end rebuild. Much of this will probably apply to other printers, in fact I will do the same on my Anet A8 and note some of the differences as I come across them.

The three main topics will be:

• Printer Calibration
• Printer Testing
• Tips & Tricks learned along the way

1. Calibrate Extruder
2. Dial in retraction
3. ???

Okay here we go. I put things back together and started calibrating again.

Test cube:

A little elephant foot action, some gaps in the top layer.

Then a benchy:

This is the worst side, odd dents, seems like an extrusion/temp issue maybe.

Not great, for comparison here is one from my Anet A8:

Plans: up retraction to 6mm from 4mm AND to move this to a calibration thread. Thank you all for your help!

@liminal you can for sure use a pi and mattercontrol, they have a .deb or you can build from source for debian based systems. The timelapse is a little more tricky, you can set up in Pi a timelapse that you fire off via a click or something and it will take snaps on a timed basis. Maybe if Mattercontrol has an API or some sort of hook then you might be able to track z changes.

The only thing I had to change much was tmp, since you are pushing more plastic it needs to melt faster. On my Anet A8 I jumped to a high volume nozzle that has a longer neck and heater block that helped a lot. Just my two cents.

Alright all parts got here. Rebuilding it was SUPER easy. I took pictures at every step, so then I could just watch them in reverse to put it back together. Just had to re-calibrate things and bam up and running!

Big shout out to the Matter Hackers support team! Thank you so much!

Tip: keep your zip ties that you have to cut off, then as you replace them throw the old ones out, this makes sure you put back on the same number that you removed.

Take a look at matterhackers troubleshooting guide and simplify3d specifically addresses this. It looks like under extrusion caused by either too low a temp or flow rate.
