I was reading that PTFE tape is not recommended as the temperatures can cause the tape to melt and give off toxic fumes: https://www.reddit.com/r/3Dprinting/comments/6l1tbf/why_dont_we_use_hightemp_thread_tape_on_hot_end/

+1 I have this same issue, I have to stalk it with a scalpel / pair of pliers to grab the filament ooze prior to the initial line. If I don't, I have to restart the print as it's likely to ruin the first layer.

Unfortunately, my new bed dips in the middle very slightly (~0.1mm) and I've had to reuse the springs to sort out alignment. There's a few variables, such as how tightly the brass standoffs are screwed in, weight of the connecting cables and manufacturing tolerances. If you redesign the bed, I'd recommend putting standoffs / screw holes in 6 places rather than 4. Also, with the new bed, there needs to be someway to hold the cables away from the print head. I used one of the spare screws and a cable tie to hold it underneath as it was clipping the fans.

@Chris D, I've just gone through several ABS+ prints, with several failures (6-7). The print I did went for 4-5 hours and the best settings I've found are: - Extruder @ 240 º C - Heated Bed (new one) @ 80 º C - Temperature offsets in Octoprint set to +/- 5 º C - Miniature bulldog clips to hold the flexplate to the new bed (that things slippery) Print stuck to the bed like glue. Sadly, when getting the prints off, the bed actually split while flexing. I'm guessing the high temps made the Print Surface sticker go brittle. If you want the detailed version, see your other post: https://www.forum.makertech3d.com/forum/general-discussion/printing-stops

Success. The offsets in Octoprint seem to work well and the new heated bed doesn't fluctuate as much at the lower temperature preventing it from crashing. Printed a replacement part for a coffee grinder and another test print. Printing in ABS has wrecked my flexplate though. When I flexed, the top has cracked. Hopefully Adeel releases an update to resolve the heated bed causing the crash.

Update - replaced my bed with the new one... on my 6th failure. Heated bed every time. It's winter and the room is probably ~6ºC but it just struggles to reach 110ºC. It's sticking like glue at 80-90ºC, but still keeps failing due to the bed. I've set an offset of 5ºC in OctoPrint and monitoring - it's slightly more reliable. My 6th print with ABS+ hotend at 240ºC offset 5ºC and bed at 80ºC offset 5ºC failed due to the new bed being super slippery and the hotend knocked it (0.12 layer height), everything ended off by 1-2mm. Signing off at 10:50pm - 7th/8th attempt, same temps as 6th attempt - bed held with mini-bulldog clips, layer height at 0.2mm will update with success / failure. Oddly enough, my printers temps have glitched / frozen around 10 mins in and are not updating. Below is a refresh after it froze - touchscreen is just frozen at the Actual T and Actual Bed temps. Probably means it will finish !! :D Hotbed feels like it's still the same temperature and hotend's printing good. Prints about 6mm now.

Using OctoPrint for my prints. My touchscreen didn't like me printing via SD card... OctoPrint did my benchy perfectly. Firmware may need to state that the bed should get up to temperature before the print starts or it could be my heated bed's a dud. In this scenario, I manually set the ABS temps and hit print without the bed at 110ºC. It carried on to auto-level then crashed: Error reported by printer Your printer's firmware reported an error. Due to that OctoPrint will disconnect. Reported error: Heating failed, system stopped! Heater_ID: bed - Printer halted. kill() called! Attempt #2 failed also, didn't even send a print job, just heating bed and hotend: Recv: Error:Heating failed, system stopped! Heater_ID: bedRecv: Error:Printer halted. kill() called!Changing monitoring state from "Operational" to "Error: Heating failed, system stopped! Heater_ID: bed - Printer halted. kill() called!"Changing monitoring state from "Error: Heating failed, system stopped! Heater_ID: bed - Printer halted. kill() called!" to "Offline (Error: Heating failed, system stopped! Heater_ID: bed - Printer halted. kill() called!)"Connection closed, closing down monitor Screen from OctoPrint: My new all-in-one bed arrived, so some maintenance and it'll be ready to try again. Bit miffed that I have to switch it out though. @Ernie Bausch, do you have OctoPrint installed? Can you check the error that's thrown up when it fails? It should retain it in the terminal.

Update: Following some discussion back and forth via email, it appears my screen is faulty (capacitive layer doesn't register touch) and the control board (CB) has a faulty Z-axis interface. Went through the following for the touchscreen: - Screen displaying and updating (hotend temps) once flashed: Yes - Checked ribbon cable: Fine - Checked all screws: Fine - Checked pins on both screen board and MB: All fine Replacement screen being sent. With the control board: - Checked for signs of damage: Nothing - Checked pins: No damage / bent pins - Tested extruder connection: To do this, if you don't want to waste filament / heating the hotend, hold the lever arm on the extruder in the open position and while holding select extrude in Ponteface - you should see the centre gear rotate confirming it works. - Testing Z-axis using extruder connection: Having confirmed the extruder worked, I moved the parallel joiner from the Z-axis pins and connected it to the working extruder pins. Once connected, I selected extrude in Ponteface and checked that both Z-axis motors moved. They did and this confirmed that Z-axis interface is faulty. End result - faulty z-axis connection - new CB being sent.
