Re: Looking for better PEI to Glass bed adhesive 200MP 468MP fail ABS temperatures

Original poster back after about 2 weeks. I apologize for over-ranting. My ABS printing is doing better. Still think we need a different adhesive. Seems I missed the meaning of "72 hour dwell" on the 468MP and 200MP adhesive product datasheets. I would call it "cure time". It means, the adhesive wil...

Looking for better PEI to Glass bed adhesive 200MP 468MP fail ABS temperatures

On my 4th PEI bed. Run ABS only on 1 of my LB Mini printer. 110c bed softens the ubiquitous 468MP tape with 200MP adhesive. Parts warp, PEI lifts off (de-laminates from) the glass. Time to replace the PEI and adhesive.

Recommendations for different high temperature Transfer Tape and adhesive, please.

Re: ABS filament damaging bed, want alternative recommendations

PEI seperating from the glass on the very 1st ABS print. Just applied a fresh sheet of PEI to the Lulzbot brand's Modular bed's glass. Used 468MP Transfer Sheets, as they are called. They employ 200MP adhesive. I print Esun ABS with 260c extruder, 110c bed. Part is about 1 inch wide and 5 inches lon...

Re: Lulzbot Mini requires huge maintenance

To continue.. The Y-endstop switches should not be on the bed. They should be on the frame. The wires too them should not have to move. When they do not move, they do not crack. Thankful for the Open Hardware design. Modified both Y-rod holder designs. Now switches are on the rod holders. Wires are ...

Re: Lulzbot Mini requires huge maintenance

Happy to have found this thread. My biggest problem is bed wiring. But first... I too run a 4 Mini "Farm" with heavy usage. Each printer runs 12 to 22 hours per day. 3 PLA and 1 ABS. All were bought used. Serial number range from 1100 to 10500. Generally satisfied with the Mini. I did buy 4 of them....

move Y-axis endstop / limit switches off the bed

Several threads discuss the Y-Axis endstop wires breaking and needing replacement on the Mini 1.0x Rhetorical question. Why do the endstop switches on the Mini move? They should be on the frame not the bed. If so the wires would not be breaking in the Y-Axis cable chain. Has anybody moved the Y-Axis...

Y-Axis cable chain problems and replacement on Mini

Lower cable chain is a problem. The one that carries wires for the heater, temperature sensor, and endstop switches. The curve or radius is too tight. The wires are over-stressed and break. On my 2 Mini printer I have replaced all heater wires, all temperature sensor wires, and 2 end-stop wires. Has...
