Quotetherippa So, tonight I installed my new extruder (happy with it, but it needs improvements. this was a remix, expect a RippaStruder in the future), and ran into the same problem you had with Marlin losing track of coordinates after autoleveling. Turns out it's a bug (it happens if your probe offset is greater than ). The new release candidate of Marlin fixes it (1.9RC2), and I got it to wby elkayem - Prusa i3 and variants
Quotepeeejayz Frustrating day today. My mk9 extruder has decided it only wants to slip on filament. It will print. But from time to time on faster areas it will slip. Also the extruder motor sounds like it's start stopping while ectruding. Whole this is currently driving me. A little mad. If I out more pressure on the filament the motor can't handle it even with more amps. I've cleared it oby elkayem - Prusa i3 and variants

Quoteanimoose I slightly regret not getting the all-metal E3D as I get a bit nervous when the temperature is around 240-250, but you can buy just the parts for an upgrade. This occurred to me as well! It looks like the only difference is the heat sink ($20) and heat break ($18), or $38 total. Since the Lite6 is $35 and the all-metal v6 is $75, with a price difference of $40, it appears $2 betteby elkayem - Prusa i3 and variants
Quoteanimoose Quoteelkayem Solved it! Sometimes it is worthwhile to go back and remeasure what you thought you already measured. When I was watching the gear drive struggling to turn, I thought I saw a problem with the motor struggling to overcome the torque required to push the filiment through the nozzle. Not the case!

Solved it! It turns out the set screws attaching the drive gear to the stepper motor had come a little loose. Good thing to add to one's troubleshooting list.by elkayem - Printing

Apologies to those with deja vu. I asked a similar question in the FolgerTech thread, but figured I would reach a wider audience if I simply opened a new topic over here... I have a new printer (FolgerTech 2020 Prusa). It has been churning out excellent prints for the last few days, with probably 32 hours total use so far. However, things changed last night...

Ok, I've got a problem now, and need help! I've had 2 days of consistently excellent printing, with probably 32 hours of continuous use. But that was then... About half-way through printing a really nice horse in ABS, the flow rate became restricted to about half, with ugly results. I removed and reinserted the filiment, with the flow rate going back to normal, but after about 15 minutes it wby elkayem - Prusa i3 and variants
QuoteIWantToBeAPrincess Thanks! that was super helpful to setting up the display I printed out a housing too. I feel like I almost know what I'm doing! It sure does look like you know what you're doing, with a custom LCD graphic inside a 3D printed housing! And love the My Little Pony looking around the corner.

Quotetherippa Your printer appears to be very dialed in Thanks! Couldn't have done it without all the great wisdom and advice imparted by you and others on this thread.by elkayem - Prusa i3 and variants
Second print off the printer. My daughter was over the moon when she saw it. I only have two datapoints, but already I would say the prints off of my $270 FolgerTech printer rival the quality of prints I get from the $2500 Ultimaker 2 we have at the office.by elkayem - Prusa i3 and variants
Quotetherippa QuoteUncertainty Hi all, Last time I posted on this thread I was probably on page 10 or so. I had built the printer successfully and then didn't really use it. I hooked everything back up a couple days ago and started printing a whole bunch of tests and cubes. I notice that my print surface gets rough and has some gaps on the infill. I could be wrong but it seems to do this when tby elkayem - Prusa i3 and variants
Quotetjnamtiw Congrats!!!! That's great! I see you mastered the 'higher end' LCD screen. I also see you put the X stop on the left and Z on the right. I'll do that on my second one! I don't see any reason right now to change wiring since everything is working great for me too. KNOCK ON WOOD. Good job. That little girl will keep you busy making things for her.

I have to say, I've learned a lot from this thread. Scanning a large number of comments has really saved a lot of time getting things up and running. One way I can give back is to summarize the major differences between the build guide and what I really did (mostly based on tips from this thread). The printer went together fairly easily. The only issues were missing SK8s (Folger sent them outby elkayem - Prusa i3 and variants
Brand new Folger Tech 2020 online, and runs like a champ. It's very first print is on the heatbed in the photo below. Transparent PLA print of "cuddling cats" (my daughter's choice!), 0% infill and no supports, printed at 190 degC.by elkayem - Prusa i3 and variants
QuoteMach For these endstops, the line between the Vin pin and the signal pin are NC, and the line between Vin and ground are NO. The signal pin sees ground voltage when the switch is actuated. You got it, Mach. Conversely, the signal pin outputs +5V when the switch is open. On my unconnected MAX lines, I needed to enable the pullup resistors so Marlin would think these switches were open.

QuoteYelloow-Snow I'm a noob but here are my thoughts. 1. Funny I just finished mine and had the SK8's missing also. That and a 360mm(?) rod. 2. did you use the firmware from here? The latest Marlin firmware with Folgertech Prusa i3 settings merged in, get it here 3. Pictures are wrong. X end stop needs to move over one. To the left. 4. I had to reverse the extruder also. It was backwards.by elkayem - Prusa i3 and variants
Hi all, new member here, first post! I purchased the 2020 based on its popularity on this forum, knowing that if I had a question there would be a whole community with answers. So here I am! Apart from missing SK8s in the kit (Folger sent them out right away after a quick email exchange, thanks Folger!), the kit went together without a hitch.
