Re: My Taurino Mega + RAMPS 1.4 is not working - 12 years ago

I tried adjusting the x-axis stepper driver potentiometer while instructing the x-axis to move and did not get any movements. Is there a minimum set of connections required to make it work? I got some MAX_TEMP errors and I changed the value temporarily to work around it. Any other ideas?

My Taurino Mega + RAMPS 1.4 is not working - 12 years ago

Hello, I've successfully connected my old Xbox 360 12V 203 watt PSU to my RAMPS board with nothing else connected but a single stepper motor for x-axis. I am trying to bench test this to make sure I get the stepper motor wiring right. I've definitely got the two coils identified so I'm pretty sure I have it at least partially right, I'm just trying to get the correct rotation direction. However

I've been meaning to do some PID tuning myself. This blog entry is what made me think of it, which has basically, the same steps, but with some extra detail. Marlin Tuning

Re: Slicing Eiffel - 12 years ago

I recently tried printing a 325% scale version of this: I ran into problems printing it (filament spool jam while printing overnight), but it was taking a very long time to slice with 0.9.9 on my old Dell e1505 laptop (it might lose its print host job to my Raspberry Pi soon). I eventually just used my beefier desktop (which has a quad-core Intel Core i7 2600k with hyperthreading for a virtual

Re: How to dual extrude with repetier and slic3r and openscad - 12 years ago

I don't think the "Plater" tab is available when Slic3r is called from ReptierHost, but that appears to be where you would choose your 2nd filament from the available saved presets. I haven't tried it, but I've attached an image of how it seems to be used.

Re: Hot end from HP 3d printer - 13 years ago

Yikes--SCSI?!? There's a term I haven't seen in a loooong time. If you don't have a SCSI interface in your PC already, you may want to abort that idea (IIRC, they're expensive) unless you mean to harvest it for parts.

Re: LulzBot TK0 - 13 years ago

This looks like some really great work--I can't wait to see the final design! I especially liked the presentation file and the stated design goals. I have been pondering some designs of my own with some similar goals. Specifically, switchable/modular head design (extruder/laser/mill/etc.), swappable build platform (since conveyor belt designs seem inherently flawed, IMO), and possibly dual ext

Re: Largest 3D printed object at home? - 13 years ago

I have a Printrbot+ with the Super-Z upgrade. I have not really tried printing anything very tall though, and it now seems like a solution in search of a problem. I would much rather have a larger print bed. Why? Because as you go higher on the z-axis the build platform movement seems to exaggerate the initial inaccuracies of the printer. Basically, it seems to get worse the higher you go. Again
