Re: files

Thank you so much for your information. I am very new and i am still learning the printer alone. I have a Makergear M2 which I like but, I want to print my parts and cant. It starts fine then about 15 minutes later the head goes off and move out of range. I am also looking for a person to re-do my ...

Re: print

Hard to say, but I think I would start by printing a known good file. The printer should have come with an SD card with couple of pre-sliced G-code files to print as examples, and I'd start with one of those. If you can't find the SD card, they should be on-line someplace. You don't say what revisio...

Re: Heat Insert Technique?

The last step in refining things was to get the holes for the inserts tuned up. I wanted the top to be beveled to leave room for a bit of ooze, but I also wanted to open up the inside diameter at the top so the inserts could be installed with finger pressure & sit vertically. The initial attempts ha...

Re: Heat Insert Technique?

As I said earlier, I do this for large threads all the time. To fit this project, I need 4-40 threads, and they have to withstand multiple assembly/disassembly cycles in the hands of people who think that if tight is a good thing, tighter must be even better...

Re: Heat Insert Technique?

I thought about that. I'll experiment a bit & report back. There's probably a dozen different ways to deal with it. I'm hoping that I can come up with a geometry where I can pre-load the inserts nice & straight with thumb pressure, and then put them on the press & seat them without having fuss with ...

Re: Heat Insert Technique?

I've had considerable success using tapped holes in my prints, or making cavities for conventional metal nuts. Especially for larger screws, I print the threads, and then clean them up with a tap. That works fine unless you expect to be disassembling & reassembling things a lot. For this job, I didn...

Re: Heat Insert Technique?

OK, that makes a HUGE difference. I need to fine tune a few things, and I'll take some pictures. I was a bit more patient in letting the temperature probe stabilize, and at 70 Vac, the Weller SP40NKUS iron from McMaster settled at ~ 235C. The insert goes in nice & smooth, with no "bounce back", and ...

Re: Heat Insert Technique?

A quick update: I dug out my thermocouple hardware, and found my old Variac. I don't have a small thermocouple probe that can go as high in temperature as the iron on full voltage. I have a 12" stainless steel probe that I held against the side of the insert tip, and that got up to 320C. Between the...

Heat Insert Technique?

I have a project that requires a housing for a small battery powered circuit. I want to use threaded brass inserts for the cover screws so the threads will hold up for multiple battery changes. The eventual goal is to make a couple dozen of the things. After some research, I ordered inserts, a solde...

Re: PETG build surface adhesion advice

I've had really good results using hair spray on glass with PETG. I use thsi stuff:
