Re: kbob and Impulse, the Rostock MAX

If it was MY printer, I'd cut replace the crimp sockets - you may have a set that's simply out of spec. I say that because I've got three v1s (all are 2013 vintage) that I've nearly beaten to death and of all the issues I've had, a) all are my own damn fault and b) never a motor connection. g. You'...

Motor Skipping

This is mostly a note to myself... My printer has about 43 days' run time now. That sounds like a lot, but I've had it almost 5 years. So it's only been running 2.4% of the time. Anyway, it occasionally messes up a print by having the X carriage lose position. Usually, the X carriage goes up too far...

Many of you have not asked me about my avatar. Why three fists? Does that even make any sense? Finally, four years later, the answer can be revealed. I'd worked up some artwork for a T-shirt, which I never got around to finishing and ordering. But now I have. Here's what it looks like on a model who...

Re: Tricklaser arm issue with bed leveling

Following up to myself. It's been another three years, and my arms are still holding together. I switched from hexagonal infill to rectilinear a while ago, and that cut way down on the vibration.

Re: Tricklaser arm issue with bed leveling

I had my arms come pre-assembled. After about a 9 months of use I had a couple of the ends start to come lose. A little super glue got them back in place firmly but they had a significant impact in my prints that was hard to track back down to it for such a small shift that they were having. Hi, Bi...

Re: Need Help with... Not sure what I'm doing.

I agree with Nylocke, especially if you're using a laptop. Most laptops do not play well with Mach 3, because Mach 3 needs hard realtime control of the PC, and most laptops have background tasks that you can't turn off. (Simplified explanation.) Mach 3, while very popular for mills and routers, is w...

Re: Slanted prints with the RoStock MAX

Binky, I took all of the rods off and measured them. The biggest disparity between the holes of any two rods was ~1.5 mm, which is fairly large. I also found that 3 of the rods did not have the holes drilled perfectly straight, which potentially skewed some of the measurements. I have put these rod...

That is what became Blue Max. The discs are from the original Indiegogo machine and all the rest of the parts were cut based on the current production parts. My laser cutter is only 24x12, so I can't cut the platform discs. g. What kind of laser cutter do you have? I have had one under construction...

Re: That's all for now!

Another change is necessary. There is some drift (number usually comes in .01 - .03 lower than it should be) caused by machine epsilon. inv_axis_steps_per_unit was defined as a float. I changed inv_axis_steps_per_unit from a float to a double (twice the accuracy) and where it was set to 1.0f / (som...

Re: Hotend temp cuts out in middle of print

Maybe your hot end thermistor came loose or disconnected. Check whether the hot end is really cool to the touch when the thermistor reads 30℃. N.B., if the thermistor is not working, the unregulated heater can destroy your hot end or burn your house down. So watch the printer carefully until you're ...

If you want to change the tone, look just slightly further down in Configuration.h. You can change the value of BEEPER_SHORT_SEQUENCE to change the sound. What's more, you can test different sounds by sending a magic G-code. My printer is in the middle of a long job, so I can't test this, but I thi...
