Re: How to easily retrofit third wire for end stops

I thought I was encompassing both high precision and high accuracy by saying high accuracy LOL. :D You are correct. I want both high precision and high accuracy. I have no plans to run other wires close to the extrusion other than the two wires encompassed within, so I should be OK in terms of short...

How to easily retrofit third wire for end stops

I have an older version of the Rostock Max kit that came with two wire end stops and mechanical end switches. Unfortunately for me, those end switches seem to not deliver enough accuracy to resume a print after homing the printer. Now that I have switched over to the smoothieboard for processing dut...

Re: Rostock Max Smoothieboard Tutorial

If M119 shows the endstops work correctly, check to see whether anything is interfering with the carriage mechanically depressing the switch. I'm using some custom carriages, and I found that the Z axis kept crashing into the endstop. It turned out to be that the endstop switch mount was protruding...

Re: Rostock Max Smoothieboard Tutorial

I am having an issue with the unit crashing the carriages when homing. I tested the end stops with m119 and it gives me a 1 for each end stop only when depressed and 0 otherwise, which is correct. I tried removing the ^ after the directly copying the config in the beginning of this thread as well as...

The Rostock Max is also an extremely capable and adaptable machine. I doubt that Airwolf's machines can beat a well-tuned, well modded Max like Mike's. For that m...

From what I saw in that video, it seems like there is a strobe timed to close to the same rate as the droplets that are coming down and the machine simply illuminates each droplet as it makes it's way to the water at the same progression, which appears to stop/reverse or slow time depending on the f...

Re: Calibration drift: why?

If you start losing Z height on the effector and it won't stay adjusted, check to make sure your stepper motor pulleys have proper flats ground into the shaft and use fresh blue loctite to hold the set screws tightly in place. If those slip even a little bit, it will make printing miserable and almo...

Re: Polycarbonate bed adhesion

I have printed a bit of PC. I use ABS glue on a pyro glass bed. It works and I have had no issues with damaging the bed. I get smooth prints usually. I also print a 10mm or 20mm brim to help maintain adhesion through longer prints.

Re: Those little holes (Warning big image)

One thing I have found that helps to eliminate those gaps is to set the infill width to be slightly less wide than the extruder nozzle width. My extruder nozzle (E3D V4) is .4 mm and I have the infill set to .39. If you leave that entry blank, Slic3r will set it to 1mm or more, which helps to create...

My burned out nozzles seem to print just fine so long as I don't try to push the envelope. I think all nozzles would perform the same. They print Taulman 645 with ease. Haven't tried the ABS with it yet, but that's next on my list.
