If anyone is interested, I made a minimalist calibration cube (shorter than the one I've been using, so it prints faster) with a notch cut out of one corner so you can tell orientation. . Btw, my dimensions come out to 20.02x20.02x8.26, so I'm pretty happyby therippa - Prusa i3 and variants

Thanks for the settings I'm currently using pla. Still learning. So far I'm hooked! ;-) After you set your auto leveling comand does it home then start your print?

QuoteNeverdone QuoteNeverdone Finally got to try and print some things. I printed a 20x20 box that turned out ok so I decided to try something else. I think I need to adjust layer height, but I am not to sure why I have the issue of the sagging lines in a couple spots. I decided to turn the temp down a little to 225 and I thought that seemed to help. At one point while the print was running iby therippa - Prusa i3 and variants

canny - when adjusting the polulu pots make sure to use the ceramic screwdriver folgertech includes in the kit or you might have some serious problems. When I adjusted mine, I clipped the ground lead on my multimeter (I bought one that has the normal...pokey things and clip attachments), would turn the pot a tiny amount, and VERY carefully touch the pot with the positive lead to get the voltage.by therippa - Prusa i3 and variants

Quotewoodknack What did you use for a profile to set yours up? I see they have a ton of different ones. They don't have our printer in their db, so I just put in the measurements 190x190x180, and told it to talk to Marlin at 250000bps.by therippa - Prusa i3 and variants

Quotetjnamtiw I'm moving right along on my assembly of my 2020. I'm up to mounting the X carriage onto the vertical frame. I just don't like the feel and sound of these bearings on the chrome rods!

The Y carriage moves easily now that I have the one bearing side 'semi-floating' but still very noisy, probably because of the metal plate vibrating and nothing to dby therippa - Prusa i3 and variants
Quotewoodknack Hmmm I'm at work now. But I'm pretty sure I tried that and got the same results. Just a small move to the left when trying to home. I just double-checked the firmware I merged vs the original folgertech, pins and axis settings are the same, so it should just be moving that x endstop to the min pins (last set of pins). You might also have to flip the wire plugged into the x-axis mby therippa - Prusa i3 and variants
Quotewoodknack I'm having the x axis issue to and have read the other pages but I'm still confused. I have downloaded therippa latest marlin and installed that. Should I move my x end stop over one set of pins and go back into marlin and change the pin #? Or is it already changed in therippa firmware update? I'm confused?

QuoteDavewerld Hi therippa, and others If I place the printer head in the middle, and home the xaxis, it moves about 10mm to the left, each time I press home it moves about 10mm away from the endstop. That's with the stepper motor plugged in like the picture on p28/38 of the config doc. If I flip that connection, it moves 10mm toward the endstop. The y axis most often does what I would expect,by therippa - Prusa i3 and variants
QuoteDavewerld Hi all, still not getting my printer to work. I emailed Folger Tech and waited the two days for a response, but the response didn't fix anything. Here's what I am at: I can connect to the printer with no issues. However, hitting the home x and home y buttons do almost nothing. Sometimes the home x button moves the carriage about 10mm, but never a big sweep to the limit switch. I hby therippa - Prusa i3 and variants
Quoteplatinum16 So I just get my 2020 Prusa i3 from folgertech and was wondering if anyone else had problems with connecting the sk8s to the frame? It says to use m5x8mm but they aren't long enough... Any thoughts? I don't think anyone who has built the printer received all the correct hardware in the order, and a trip or two the local hardware store always had to be made.by therippa - Prusa i3 and variants

Did you ever solve this? I'm having the same problem too Edit: Figured it out. Z_SAFE_HOMING doesn't work when X home is at a max endstop. Had to mess around with the configuration and flip the X motor connector, now it works fine. Also, turn on DISABLE_MAX_ENDSTOPS.by therippa - Prusa i3 and variants
