Another Foldarap November 12, 2013 04:23AM |
Hi, I just thought I'd share my build
I've recently acquired an interest in 3D printing (when a friend of mine brought his delta round to me to repair his controller board after he blew up a MOSFET) and after some research, decide that the Foldarap is the one for me. I've sourced all the parts myself (using the BOM from the wiki site) and used a lower cost 250W LED strip light power supply (12V) to drive it. As I've a fair bit of experience with electronics, I've etched my own Gen7 based control board (plan to mount it on the side of the printer where there's just enough room for it) and plan to be running marlin firmware on it. I've decided to mount the Z endstop at the top (rather than at the bottom) and the first print will likely be a bracket to mount the Y-endstop in the same manner as the Mendels (after calibration of course!)
Next up I'm etching a heatbed on a piece of FR4 single sided (50W) that I'll insulate with Kapton and put a glass surface above it to print to. The attached image shows the status of the machine before the weekend, I've since tidied up the cabling with spiral wrap and been trying to get all the motion working with the marlin firmware
Many thanks to Emmanuel for designing this, it's awed a few of my friends and one chap would like to borrow it for exhibitions (as it's a bit more portable than his Prusa!)

And last night I debugged my Gen7 electronics controller board and have it working in all four axis (X, Y, Z and Extruder), it homes correctly as well, so now I have to figure out the print volume and calibrate correctly - I'm wondering how much microstep I should run on the controllers to give good resolution and acceptable speeds, or if I should switch to an ATX power supply (as I have a few of those available) as I wonder if the power supply is suffering when it tries to drive everything (supposed to be good for 250W and I don't think I'm putting more than half of that load on it)

Nice build, thanks for sharing !
250W should be enough, a friend is running a big MK2 pcb with a cheap 120W on a FoldaRap-Mendel, even while his last print took 13hrs ^^

BTW where are you based ? Just to add you on the map : [goo.gl]

Well, this weekend I made the headbed
Then had a go at a basic calibration print (been using this as a dry run test beforehand, so I've learnt the basics of the .stl->slice->print toolchain)
Thought it looked pretty good, so did a test run (happy with it!)
I did notice some oozing around the joints in the hot end when I did a longer run, so I've had some tweaking to do. Seriously considering printing a holder for a J-Head or similar and running one of those
I did a little more calibration of the software and improved the output a bit
And just finished running through one spool holder base (just fits the print bed!)
All in ABS (all the plastic parts were printed in ABS by a friend with a couple of Prusa's)
