Welcome to the SeeMeCNC Community

Correcting for background information. I used a multimeter to measure the temperature and the value is less than 250 º C ( is not 150 º C) around 240 ° C. I use white ABS plastic 3mm.

hello, My extrunder not print correctly. I opened it and realized that part is charred teflon (picture). However, I used temperature below 150 º C. This darkening is normal? I printed a few times. I would appreciate some help. I think extrunder not eliminate the plastic constantly. So I suspected th...

I need to update also. I look forward to new posts.
thanks.

Tom and kilroyo, Hi, I changed from 3000 to 500 mm / min in MACH3, but the problem continued. My settings are below.

256mm/min? no forum http://forum.seemecnc.com/viewtopic.php?f=22&t=49 is set 3000mm/min. http://forum.seemecnc.com/download/file ... de=view.is that right?

My printer does not print well. I do not know how to adjust it. Please, I need help.
At the end of the video, the ABS does not leave extrunder. Even with the same temperature (215 to 220 º C at the nozzle).

What is the maximum temperature of the Teflon (4mm)?
Anyone know the manufacturer's specifications?

I've never seen one of these working.

Thank you.
the correct setting:

I need help setting up.

I need help. I did the drawing in sketup, converted to G code by slic, and I load the Gcode MACH3. Do not adjust extrunder on the table. (G92 E0 reset extrunsion distance).

Why the seemecnc sells (Natural ABS Resin 2 lbs)?
You can make the filament?
Does anyone know how to do?

I read it. If I did not tighten the screw as the video, the inner shaft does not rotate (abs plastic).

I need help.

The noise starts when I tighten the screw in the center gear.
I do not think it's the engine. The noise starts after tightening the screw. watch the video.

My A-axis is making too much noise, too. Adjusted speed rate of 1% to 20% (MPG mode) and the noise remains. Realized adjustments in the menu config \ engine tuning \ A-axis \ velocity. The noise continues.(Mach3)

Hello, The motors are moving. I changed the Active Low Enable1, Enable2, and Eneble3 Eneble4 of (V to X) of the file (SeeMeCNC 4AxisBoard.xml.zip-H1) I am very happy with it. results: Solution of the problem: http://youtu.be/3fs9UxxfHAc Movement of motors: http://youtu.be/ZxeYQYOmwus Now I can calib...

Thanks for the help Andy Wander. Glad you have knowledge in Mach3. I am noob in Mach3, but I have knowledge in electronics. To view videos you must have knowledge in electronics. I think I understand now. In videos 1 and 2, I did the measurements with the RESET button(ON) pressed Mach3. So had no pu...

-When you say, "the engines are stopped", do you mean that Mach3 is in a state where it should be sending step pulses to the TB6560 board(the Mach3 onscreen DROs are changing), but the stepper motors are not turning? Yes. Mach3 onscreen DROs are changing, but the stepper motors are not tur...

The engines are stopped. The output signal (TB6560) is null.
The port I'm using is the Ex800 (LPT3 -PC- port parala off board). It is the same port that I use in dot matrix printer.

Video 1: pulse signal (of Mach3) measured in jumper. (no noise). http://www.youtube.com/watch?v=mQKdx8t87b4 Video 2: Null signal measured at the output to the motor. (It is noise) to move the probe of the oscilloscope. http://www.youtube.com/watch?v=QQw7S320g84 The engines are stopped. The output si...

disregard this post.(edited)

I performed the procedure (3.2 - Remove Jumper and The Optical Isolators) manual. Measuring the signals of the jumper 1-8 which correspond (TX = 1, x axis), (2 = indicator + X or -X activated; X axis) and 3E4 to Y axis, 5e6 to Z axis , 7e8 to the axis 4. The motor does not move. Watch the video http...

I did not use the jumper in place of optos because johnoly99 said many printers do not need jumper mode. (http://forum.seemecnc.com/viewtopic.php?f=22&t=49). 3 -Installing the Mach3 configuration file with SeeMeCNC-H1-4AxisBoard.XML. MDI used the menu to move the axes but the engine did not act(...
