Give tech support a call, I ran into this when I first received my printer and they solved the issue for me.

@rsteel517 Thanks for this but the first question (there are no dumb questions) does the Marlin firmware used in a Smoothie board? (This might be a dumb question ).

@cfitts90 I have not tried it at the moment, I have the "Smoothie" board and wasn't sure if this was compatable, still learning about these systems at this level.

That one worked, thanks!

Apply LocTite 222 (purple) to the Y-Axis mount under the platform and to the retaining screw of the extruder, keeps these from vibrating loose. Purple Loctite is formulated for small threads and ease of removal when needed.

Our Provincial Health Authority requested a modification for the face shield before they would certify them for use in clinics and hospitals, add to the print time but look pretty sharp.

Kept my printer rolling continuously and learn quite a bit about the changes could and couldn't make.

It always bugs me when people as for advice and then never return to inform the forum of what the fix was so here goes.

Received a new harness and probe today, started with the probe and no response from the macro tests to extend and retract. So ran the new harness to the old probe and it responds to the commands, well I have seen this before.

Temporarily looped the harness in place and tried to calibrate the bed level and lo and behold it worked, I learned the first clue to proper operation is the probe extends on the way down, something I failed to note before so if it doesn't extend, stop it NOW or it will try and drill through the print bed.

So I have an intermittent break in the old probe harness, it must be a small break that is making contact when the harness is in a specific spot...like the center of the bed for z offset calibration. Wires break over time, at least it wasn't the motherboard..

Now to figure out how to add the new harness to the existing wire bundle.

I knew nothing about 3d printing but my research led me to the Pulse because of it's ability to do materials like NylonG and NylonX as I had a specific project in mind. I decided to load it up including the 32bit board and magnetic print bed and print dry system since I had the funds available at the time.

For a complete novice it came out of the box and worked, I was printing like a pro, there was a learning curve involved and some total failures but I complete that project on time. I like the printer, it's rock solid and the all metal hot end gives lot of flexibility when choosing filament. The magnetic bed means I have different print bed materials that I can change quickly and easily and I am screwing around with different tape and hair spray.

A year later I am still having fun but now I wish either MatterControl would be more flexible and usable like Cura or PrusaSlicer as working on face shields I don't have the luxury of setting layer by layer settings and the later versions of MC seem to lack even choosing a nozzle size. I have learn a lot with this printer and I like it still.

I am having some issues at the moment and I am sure it will all get worked out shortly. I can't comment on what the difference is between 8bit and 32bit sorry, but I like to up the game when buying new so took the plunge.

Would I buy another? Most likely, if I could easily use another slicer, definitely, I still have learned enough to deal with G code and modifying the code to use Cura at this point, not sure if Simplify3D is worth the money either.

Well I jumped the gun on this one, the probe responded macro commands right up until I ran a bed level calibration routine. It heated the bed to it's target temp and then attempted to ram the nozzle through the print bed..

The probe no longer responds to macro commands from Matter Control.

I went to the z offset calibration (big mistake), it homed then centered, bounced the probe three times as normal and then I went through the steps to calibrate the z offset.

It now clogging the nozzle when trying to print do to basically riding on the bed surface, I have tried to nudge it up now several steps but still no joy. I guess I will wait for MH support to get in touch.

Sigh.
