Thank you @tinkergnome. I did try bending it a bit in, and even going ~1mm more than the spec you linked. It was still scratching and I suspect it is some manufacturing tolerance issue.

Thank you! Closing this thread: I solved the issue by printing a small collar for the part that hits the limit switch 3mm early than what it used to. This creates enough clearance.

Does someone mind actually sharing what the clearance between the left fan shroud and the left wall is on a UM2+?

Yeah I did update the firmware, verified that the correct firmware is on it. Even flashed it manually from hex file. I then also did a factory reset to clear up the EEPROM. It makes a screeching sound and I can see scratched up plexiglass of the left wall 😞

Hello Experts, I just upgraded my UM2 to a UM2+ with the Extrusion Upgrade Kit. I followed all instructions, double checked, and completed it with uploading the UM2+ firmware from within Cura 4.5. I notice that when the head homes or whatever process causes the head to go from front-left to home position the left shroud of the fan (the sheet metal) scratches against the plexiglass left wall. How do I fix this? I don;t understand why it would scratch against the wall because with printer off, when I slowly move the head left, as soon as the limit switch clicks, there is 2-3mm gap. So why is it scratching when in operation? Any help is appreciated! Sid

Thanks for this post SandervG! As someone who fell for a scam just recently, I would not deal with anyone who refuses to use Paypal Goods and Services . Do not use Paypal friends and family or Zelle or any other mechanism. Additional steps you can take as a buyer: Goto archive.org and take a snapshot of their post. This way if they delete evidence or alter it, you will have a trusted 3rd party source of the original post. Have the person Include the link to the original post in their PayPal Invoice. Have the person send you a video of the printer with today's newspaper or NYT website open or something. Do not worry about inconveniencing them. You are buying, they are selling. You are the customer and they should be doing extra work to make a deal work. If you fall for a scam, call your bank and then file an FBI report here: ic3.gov. It may be slow, may not seem like the feds will do anything, but eventually it will happen. Additional Steps as a seller: Ship via tracked and signature required. This way a buyer cannot open a dispute with PayPal that you never shipped. Take a video of you packaging and a photo of the final box for dispute related incidences Do not skimp on the insurance for the package Only ship to PayPal verified addresses. If the buyer does not have one, ask them to do it (it takes 2 minutes).

Oh crap.. Did you deal with durstey as well? If so DM me. I will share the FBI report I filed and you should too.

@SandervG your guess is spot on. It did come with a roll of blue PLA and my guess is that it dates back to June 2014. I have ordered three rolls of Ultimaker materials and will test with that beforr tweaking anything. I also printed the hollow tetrahedron (I think called line tetra) and it came out perfect with zero stringing. The retraction on it was perfect. Thank you for sharing what the various fearures on the MiniCal meant!!

Hello, I just bought a lightly used UM2 from a fellow community member (it has ~28 hours on it only, so like-new). I printed the MiniCalTest file that was on the factory card. I am not sure how I am supposed to interpret the test results? I see some stringing and for the wedge, I don't know what that's about. Pictured below, please advise and is there any thing I can tune?

This dude scammed me out of $850. A FBI complaint has been filed. Anyone else dealing with them, please beware.

Sent a dm.

Hi Payette, I am interested. Can you please DM me? Thanks! Sid

Hi there, is this still available? If so, can you please DM me and start a thread?
