I’ve had a MK4S for over a week now, and 100% of the prints I’ve tried to make on the textured sheets have partially or totally failed. PLA prints beautifully on the smooth sheet, but PLA, PETG and ABS, I think I could print on the surface of a 10 inch tank of oil with more success than the textured sheet. Plastic doesn’t stick to it. I’ve wiped it with isopopyl, I’ve washed it with dawn…it’s a bad print surface and I want my money back.
I had issues with mine, nothing was sticking to it causing 100% failures. I forgot where I read it but I ended up scrubbing it good with one of those slightly abrasive green pads in warm dawn dish soap, drying it with a clean microfiber cloth and putting it on the bed with the heat set to 60c for a few minutes. It now works extremely well with pla or petg, I just wipe it down with a bit of 90% alcohol between prints. Never had any issues with the smooth and satin sheets.
Kitchen sink washed and rinsed. Water run as hot as I can get it this time of year. Drain plug installed, textured sheet washed with a fresh green Scotchbrite pad under hot water and Dawn dish soap. Each side scoured in horizontal strokes, vertical strokes, diagonal top-left to bottom-right strokes, diagonal top-right to bottom-left strokes, in counter-clockwidse circles in horizontal strokes, and clockwise circles in vertical strokes. Repeated 3 times each side. Dried with laundered microfiber cloth. Placed on printer heat bed and heated to 60C for 5 minutes per side.
This makes the 4th, 5th and 6th time this sheet they tell you not to submerge in water has been washed in a sink full of soap and water.
Brand new spool of Printed Solid Jessie PETG filament loaded, corresponding filament preset selected in slicer. Tool caddy with assistant discs at sharp corners sliced, sent to printer, Z offset set at -0.025mm, 1 glencairn of small batch 90 proof straight bourbon poured…
Edit:
It seems the only thing you can improve at all is scotch instead of bourbon. :P Jokes aside: is your bed heating or does it just shows to heat in the display?
What is real? How do you define real?
I mean, I haven’t had the torque wrench calibrated a split second before the wrench was applied to the faucet handle by state and federal members of the Department of Weights And Measures, but the print bed is hot to the touch when it’s finished printing, yet it doesn’t burn my skin like the one time in A&P school when I set my welding filler rod down over my pliers, then reached to pick up my pliers, burned my thumb on the welding rod and smelled it before feeling it because at the temperature steel melts your nerves die faster than they transmit pain signals…I strongly hypothesize my bed heater is functioning correctly and accurately.
Don’t go to airplane mechanic school, kids. That’s a career for old and mentally ill people. Become an influencer, sell NFTs, become a prostitute, do something healthy, honorable and productive with your life. Let aviation be that thing two idiots from Ohio did in North Carolina that one time and dismiss it as a fantasy for degenerates.
