Hello,
I wanted to give you a feedback with my now functional Foldarap and also ask a view question because I still have some minor issues.
I printed the active cooling part available here : [www.thingiverse.com], it doesn’t seems more efficient than this small part : [www.thingiverse.com]. I believe the holes are too small…
I had an issue with the peltier… it stopped working after one week… a brought a new one at 20€ (not a 5$ Chinese one) and this one seems to be a lot more powerful, the plate is hot on 2 minutes against 10 for the original one. I also added a cooling system on the cold side (or heating since the back is cold) because it might be why the first one stopped working…
I still have to shorten the wires, I discovered too late in the manual the size of the wires…
I successfully printed a lot of parts using the Slicer configuration provided by Emmanuel [github.com] but strangely when I try to accelerate a little the extruder motor seems to be missing steps.. .this might be the speed limit with this hot end.
Now for the part where I need your help :

Now for the part where I need your help :
- I a printing on glass (with no kapton) which is working fine for small parts, but seems not to be efficient with bigger parts (cf picture attached)… I will try back printing on the aluminium bed with kapton but I will gladly take advice from you to avoid the corners to peel off….
- I don’t know how to print from SD card… I can’t find documentation on the web… I am using pronterface, I click on send to SD and nothing happened… I don’t know how to debug it and also I didn’t find if there is limitation on the SD card… is a 16 GB card too big ?
- I seem to have surges issues… or maybe something else (that’s also why I want to print from SD, to remove the computer factor) .
- When I am printing from the computer the print stops (nothing written in the pronterface console but the connexion from computer to the printer is cut, I have to disconnect and reconnect) randomly… sometime I have no issues during one day, sometime I stops every 2 to 15 minutes… with no special activates in my home.
- I think it is about power because when I start and stop a 12V halogen light with its coil transformer it cuts the connection and the print almost every time and I can see some spikes (with my old oscilloscope) on the output of the power supply of the printer.
- I tried to put some ferrite on the cable with no change and also add capacitor of 47 or 100 or 1000 µF on the output of the power supply… I don’t change anything…
- I also tried to change the USB cable, and with another one of 1m it seems to be worse… (also this cable is forking fine with other material)
Thank you for reading me and for your advice.
Regards,
