Re: Idea for new auto "Z" leveling - 11 years ago

QuoteRobdizzThat idea that you posted would work for my application if it were to be able to stop the "Z" axis once the connection has been made. Just connect it to RAMPS instead of a battery and buzzer, should work. I'd also swap the PCB squares for aluminum foil, and connect the wires to the binder clips.

Re: Auto touch Z end-stop - 11 years ago

Normally there's a nut on the threaded rod inside the X axis motor mount and idler. What this object does is relocate that nut to the yellow piece. Yes, the yellow piece moves up and down the threaded and smooth rods. The X axis motor mount and idler ride on top of the yellow piece. When Z axis is moved down to zero, the extruder hotend will touch the build plate and stop, but the yellow pieces w

Re: Makerfarm Prusa i3 8" First Build + Assembly - 11 years ago

Looks good. I just got mine last Saturday, and finished assembly on Sunday. Unfortunately I have to wait until next Monday before my power supply arrives, so it's just sitting pretty on my desk right now. I decided to paint mine before assembly, and I also added some flexible 12v automotive LED strips. I was lucky enough to receive a black extruder, but unlucky to get a tan J-Head. If anyone

Re: Prusa i3 6" Z motor to threaded rod connection prob - 11 years ago

Makerfarm has some metal z-axis connectors available in the hardware section if you want to try them, I think it'll be the 5mm-5mm ones. Otherwise you could try to put a zip tie around the plastic tubing to help hold it onto the threaded rod.

Re: Endstop stopping wrong side - 11 years ago

Have you tried flipping your motor cable over where it plugs into the control board? Sounds like the motor's moving opposite than what the software is telling it.

Re: LulzBot's TAZ Printer? - 11 years ago

If you want to build an extrusion frame and don't want to pay for the aluminum, you can print out plastic t-slot beams instead.

Re: help with Prusa i3 - 11 years ago

Here's some more T-slot beams. I'm planning on using these. The 20x40 beams for the base of the printer, and 20x20 beams for the Z axis frame.

Re: Prusa I3X DIYtechshop - 11 years ago

Quoten9jcv I think from what I have read on the forums the tubing is better at eliminating Z wobble, rather than couplers. Did I hear right that a small ball bearing inside the tubing between the motor shaft and the threaded rod would help, too? And to cover the tubing with heatshrink to help keep it in place?

Re: Problems with x motor nut trap - 11 years ago

If your z-axis nuts are still sufficiently trapped to let you keep printing, you could print out some of these to relocate the nuts: You'll just be putting the nuts in a different trap, and the x-motor and x-idler will ride on top of them. As a bonus, no more plowing the nozzle into the bed, the x-axis will stop when it touches even if the z-axis keeps going down.

Re: help with Prusa i3 - 11 years ago

If you don't use a frame, how are you going to hold the tops of the z-axis rods in place? I've been looking at some printable t-slot beams on thingiverse. Perhaps those might work for you?

Re: Magma Hot End w/ Marlin v1 - 11 years ago

I'm still about a month away from placing an order for the Makerfarm i3, but I think it comes with a RAMPS. Colin told me last night that an ATX power supply "performs better and gives better quality prints." I'm trying to figure out which way to go. I am leaning towards the 12v 30a power supply, though. Trying to figure out what extra materials I'll need if I get it.

Re: Use M2 printer at work to make a Prusa for home? - 11 years ago

Re: First Print, Thoughts? - 11 years ago

Picture #8, is that a shot of the bottom of the cube, or the top? If it's the bottom, it would seem to me your nozzle isn't close enough to the bed. As I understand it, the first layer of filament should be more squished together than what that's showing. That may be why you lost adhesion and the object moved during printing.

I don't know if this will help you or not, as it's for a different style i3, but it describes how to modify the latest Marlin firmware to work with the i3.

Re: Auto touch Z end-stop - 11 years ago

I'm not interested in it so much for the bed leveling, but for its method of keeping the nozzle from being plowed into the build plate. Once it touches, it stops, no extra force pushing it into the glass. It seems a safer method, to me, than a regular z-stop microswitch that might fail or be wired wrong. Perhaps a hybrid might work better, uncle_bob? Have the X-axis floating on the platform like

Re: Printrbot Simple w/ Upgrade vs Prusa i3 - 11 years ago

I'm planning on getting the 8" Prusa i3. Cheaper than other kits I've been looking at, and much simpler assembly. The Prusa Mendel i2 I had considered until I saw all the fiddly adjustment of nuts to get everything perfectly aligned and calibrated. The Makerfarm Prusa i3 is already pre-aligned and calibrated, according to its maker.
