Re: Folgertech Prusa I3 Acrylic, First print questions. - 10 years ago

Why risk screwing up your heater for $12? This is some heavy duty glass that conducts well. You can spend even less by finding a mirror at one of the WalMarts of the world or get a piece of glass cut at Home Depot! You'll be glad you did. Then throw the painter's tape away and get a can of the cheapest hair spray you can find. Heat the bed to 70 and you will have no problems. No raft or b

I also get this error message and processor lock up occasionally on an initial start up. I've been running for about 7 months now with the same wiring and same thermistor setting so that's not the problem. I believe it has more to do with a temperature band that MARLIN wants to see as heating progresses. Just don't know yet where to look. Two searches show this the only one with this problem

If the original printer was set up like that, and now the fan is left on, obviously it was learned that this would result in extruder clogs. It's called progress. Just leave the fan on and move on.

Re: Help please - can't get good print quality after bed levelling - 10 years ago

Also, don't ASSUME that the Z height is correct once you set it. Run anything, stop it after the skirt has printed and measure the height of the skirt. Is it 0.1 (zero set point) plus your layer height or is it higher. Often you have to fine tune the zero position.

1) It makes no difference which way you hook up the wires since DC current doesn't care which way it flows through a resistor. That's not the cause of your problem. 2) Do not use those charred connectors!! They are dangerous! You probably either tinned your wires before you inserted them, which is a no-no according to electrical safe practice (although many do it) or you didn't tighten down t
