Topic: Please Help with Repetier Host!

I guys, I'm trying to use RH to make some complex prints but I don't know how configure the settings for the Press.

Here is the steps trying to make some prints with RH:

1. Send code M851 Z3.90 to set the Z probe
2. Send code M500 to store the value
3. Warm the extruder and bed, load the model and print.

But the hotend don't touch the glass and don't extrude any filament, look this video stk00lVPxt4 in youtube please:

Sorry for the bad quality.

Thank you  a lot for any help.

Sorry for my bad english. Gracias.

Re: Please Help with Repetier Host!

If you have set your Z offset in Soliprint you shouldn't have to do your first step. I ran into that problem.

I would suggest double checking your Z offset in Soliprint (I suggest V1.0, but that is just me.) If it looks good, then try printing in RH without sending a Z-offset.

Jmmmm... I wil give a try and see with the Z offset in Soliprint tonight.

But why the extruder don´t extrude filament? The hotent is 215°c and manually I can extrude normally.

hmm

Have you checked to make sure that the extruder gear is tight on the shaft? A lot of the Press printers have arrived with loose set screws.

If the bed is not auto-leveling then run G29 in the start Gcode, but when you extrude manually are you pushing it or are you telling it to extrude?

Hi guys.

I set the trimpots to the SD values, x1 y1 z1 e1.5, checked the extruder gear and look fine and get some decent prints.

Also checked the gear extruder and looks fine, extrude filament without any strange noise.

In RH I send the G29 to the start of the G code but only drops once time and start to "print" in the air without extrude any filament, please look in youtube the video NRlMBIwmUEo to see what I mean.

Why the printer is getting a Z zigzag when is printing, something like this youtube video 7BaqhgY.

Thank you a lot for any help.

Gracias smile

In the top layers I got holes in the print, I set the extruder to 240c and bed to 90c.

Re: Please Help with Repetier Host!

Hey to get the z-probe to work at the start of a print. Open up the slic3r settings, go to printer settings tab, click Custom Gcode, and use this for the Gcode Start:

G28 ; home all axes
G29 ; z-probe
G1 Z5 F5000 ; lift nozzle

Also, if the hot end is loose, try tightening the thumb screw on the extruder assembly. The one behind the clear cover. (Have to take off one thumb screw to get to the other. Make sure you do all this obviously when the extruder is cool.

Thank you a lot, I will give a try and see if work.

Edit: The screws are very very tighten but the hotend keep loose.  O.o
The code works on RH, but with some Z off calibration problems hmm

Here is some print test, but looks like the printer have some Z belt problems

Re: Please Help with Repetier Host!

Make that "G28 X0 Y0". Not "G28".
My printer didn't used to care, but I think after I ran SP 1.1.2, it started to.
With just "G28", the G29 returns "echo:Home x/y before z" and skips the bed probe, leading to air prints.
