Re: Tec 4 starts 2 to 3 times and (sometimes) turns off while printing

My printer is not new, but I've got firmware upgrade recently - Marlin 1.1.8 I have printer shutdown problem when heatbed was regulated by PID, bang-bang mode is seems to solves that. The power supply seems to work less stable with the PID controlled heated bed, although I never had a drop-out whil...

Re: Fan connections?

where is it possible to see more info about wiring? AFAIK, there is no official documentation of the board. It looks like it is based on RAMPS1.4 though, which might help with reverse-engineering. some where here I heared that 5V in "MAIN" might be converted to 12V by desoldering some resistor. It ...

Re: Using a FELIX 3.0 with LabVIEW

You should first verify that the serial communication is okay. Normally, upon opening the port, the printer will reset and send some messages. Then you can enter commands, e.g. "G28 X0" for homing X or "M114" for making the printer send the current coordinates. Repetier sends some initialization com...

Re: Using a FELIX 3.0 with LabVIEW

I don't get it. What could be simpler than sending G-code over the serial port? Or did you try and it didn't work, possibly because you forgot to end each G-code line with a line feed character (ASCII-code 10, or "\n" when using fprintf in C)? The printer firmware is a G-code interpreter. It only ge...

Re: Felix Tec 4 Upgrade: Installed

Thanks for the post. I wonder how effective the heat barrier between the hot and cold end of the new extruder is in comparison to the old extruder with the PEEK element - and whether the PEEK replacement will become hotter on its surface than the PEEK (at the same extrusion temp, of course).

Provided the fan is working, and I guess it does, the problem is probably a faulty output transistor. See also http://www.felixprinters.com/forum/view ... =11&t=1652.

Not sure if I understand the question. Just connect it to OPT instead of MAIN (like shown in the assembly manual for the dual extruder). See also http://www.felixprinters.com/forum/view ... 6825#p6825.

Re: Looking for OPT1/OPT2 documentation and free Pins

I have already (successfully) attempted to use the thermistor port, although in this case for extr1 (pin 15). Interestingly I observed temperature error in the order of 17 degrees even before turning on the heater element. Yes, errors are expected to be higher at lower temps. The PT100 circuit requ...

Re: Looking for OPT1/OPT2 documentation and free Pins

Various circuits on the board appeared restrictive and was considering soldering in a bypass over the resistor. I don't get why you are not using the "thermistor circuit". Instead of connecting the E3D PT100 amplifier output to 42, you connect it to the thermistor screw terminal. Of the two screw t...
