Re: print fails at same point [solved] lesson learned - 9 years ago

These are my new kossel motor frames, effectors, etc. These are printed on the same machine as the failed prints. Only difference is I switched back to the MK-8 print head the one on the left and not the knock off V6: And these are the ones with the knock off V6: So what it came down to is the knock off V6 would not print well on larger prints. On smaller prints it look great.I also tr

Re: print fails at same point - 9 years ago

So after spending some time on IRC and learning about my "metal j-head v6" i pulled my printer apart and put the mk-8 head back in retried the print and it came out almost perfect couple very small separations so I will try another at a little higher temp. So maybe the thermo reading is off on my "j-head" or the fact of it being a knock off J-head is the blame. Can I measure the ohms of my the

Re: Z-steps per mm 8mm rods Folger prusa I3 2020 - 9 years ago

The prusaprinters.org site gave me 1600 and it is at 1585 now, I still have this odd print separation issue though in abs on taller printers. 1585 was the z-steps i need. and the print separation was from my knock off V6. If this is seen by a ADMIN please mark as solved.

Re: Prusa i3 shifting, im going crazy! - 9 years ago

Is there a binding issue? with the printer unpluged and not hooked to usb if you slowly push the bed and x-carriage back and forth see if there is any tight spots. Is the print still stuck firmly to the bed is it coming loose? Are any wires hanging down bumping it? How tight are the belts and is the motor hot after being in use a few minutes (I saw you said these were good but I added adjuster

Tom's videos have been a HUGE help. I am printing ABS with 235 at the nozzle and 110 on the bed. Belt tension is a HUGE issue. I printed my way up so to speak. I printed my first set of upgrades (belt tension adjusters) that looked like crap installed them printed a new set which looked great and so on.

Re: Heated bed question - 9 years ago

Quoteifrisbie Hi Everyone. I am returning to a project from over a year ago I had to abandon due to RL. Last I was working on my Prusa (I guess you call it an i2 now) I had the PCB Heated Bed MK1 with glass mounted to it with clips and the thermistor taped to the edge of the top surface of the glass using kapton tape.

print fails at same point - 9 years ago

I have been trying to print some kossel motor frames and the prints always fails I just noticed though they have always failed in the same spot!! I have tried enclosing to avoid drafts, raised the hot end temp up to 235 and the bed to 110. I have tried adding a skirt and also printing a brim (though only 12 layers high). I have changed the infill percent down as low as %10 and kept my walls to

Re: Heated bed issues - 9 years ago

I tried kp 10.00 ki .023 kd 305.4 Could not get the bed over 85 degrees. So frustrated I ordered a new PCB heater in hopes it was my fault and I damaged the bed trying to unsolder the wires when i flipped it. I have seen people with this issue change the thermistor from table 6 to table 1 will try it.

Heated bed issues - 9 years ago

My heated bed WAS working ok just took forever to reach temp (25 minutes). So when I overhauled my I3-2020 I flipped my heater over so grid side was up added a piece of cardboard between aluminum plate and PCB, then ran PID autotune with plugging the new values in my firmware. Well now I can not get the bed to 100 degrees by itself. If I use a heat gun to get it up to temp then the temp will not

Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 9 years ago

Any thoughts on this? stepper skip, bad stl file? bad slice? Maybe I should mention I was blasting my build plate with a heat gun to get it up to temperature just before the print started so maybe those are thermal induced?

Ever since i flipped my bed I can not get the temp over 90 uhg time to trouble shoot. Looks like I loaded my PLA profile and not my ABS so bed was doing as it should!! Changed back and looks good.

Current state of the printer. I still need to add the adjustable Z-endstop, level the bed, and tidy up some wires. to tired to do it tonight though. May not show well in the photos but I also flipped over the bed heater over to grid side up and added a piece of cardboard between the heater and the aluminum bed plate.

Has anyone made any Y end stop mods? I do not like how it's set up and I am slowly learning 123 design. Just curious if anyone has made some yet. I plan on doing a MAJOR overhaul this weekend and one of the things I would like to address is bed heat up time. Will start by flipping my heater over grid up but I am curious about what people are using to insulate the aluminium plate from the heater.
