PrusaControl - official thread  

Re: PrusaControl - official thread

In the past with other printers I've been able to use Repetier-Host - it loads models, slices, allows full control of slic3r settings, previews the plate, and directly drives the printer. Now I need to slice the STL file, save the gcode on the disk, and then drive the printer with pronterface. It works fine, but is a multi-step procedure, and seems at odds with Prusa's "just hit print" paradigm.

Is there any easy way to import Prusa settings for printer and filament into Repetier-Host so I can use that? Admittedly I have not tried yet, as my MK3 is only new, but have others had experiences?

Some wishes: when PrusaControl grows up, I'd really like it to be able to do what Rep-Host does.

As another option, I'd like to have USB mass-storage access to the SD card in the printer over USB, not just the super-slow upload in pronterface. Then I could see it from the PC and save the gcode there directly.

Re: PrusaControl - official thread

When I slice something with PrusaControl (Mac, version 0.9.4_415_beta), the progress bar counts up rapidly, but when it hits 100%, it sits for a very, very long time with the message "Generating G-code preview" in the lower left. This can be several minutes to even an hour, before it eventually finishes, and I can save the g-code. In Activity Monitor, PrusaControl is using 99% of CPU, so something is definitely happening.

Slic3r will generate the gcode from the same stl files in less than a minute.

I like the simplicity of prusacontrol and some of the other elements, but this delay between hitting 100% and being able to save is making it near impossible to use with all but the simplest prints.

Is anyone else seeing this? Is there a fix?

I'd just like to bump this.
Anyone else seeing it?

Re: PrusaControl - official thread

Hi, I encountered a problem using PrusaControl trying to print the cat ring shown below. PrusaControl for some reason doesn't create first layer of the ring so the second layer has no support and collapses. Slic3r reported 4 manifold auto-corrected errors but dealt with it fine. I also tried to repair the model with Slic3r and then use PrusaControl but the result is the same.

Is the problem between my chair and keyboard or is it PrusaControl?

How can I edit the starting gcode that extruder heats up after mesh bed leveling?

In printers.json I've changed it to

"start_gcode": "M115 U3.0.12 ; tell printer latest fw version\\nM140 S[first_layer_bed_temperature] ; set bed temp\\nM190 S[first_layer_bed_temperature] ; wait for bed temp\\nG28 W ; home all without mesh bed level\\nG80 ; mesh bed leveling\\nG1 Z100 ; raise Z axis before heating\\nM83 ; extruder relative mode\\nM104 S[first_layer_temperature] ; set extruder temp\\nM109 S[first_layer_temperature] ; wait for extruder temp\\nG1 Y-3.0 F1000.0 ; go outside pritn area\\nG1 X60.0 E9.0 F1000.0 ; intro line\\nG1 X100.0 E12.5 F1000.0 ; intro line\\nG92 E0.0",


But gcode still gives

M83 ; extruder relative mode
M104 S215 ; set extruder temp
M140 S60 ; set bed temp

In printers.json I've changed it to .....

In Windows, there are two copies of the printers.json file.

You must edit the one in c:\Users\{YourUserName}\.prusacontrol

The one in c:\ProgramFiles\PrusaControl\data will have no affect

Also, make sure you are editing the correct section (MK2 - MK2MM - MK2MMsingle - MK3)

Hope this works for you. I tested it here and it did.

Re: PrusaControl - official thread

Thanks Jerry, I was editing the one located in Program Files 😉

Re: PrusaControl - official thread

PrusaControl is using the same presets as Slic3r PE so I'd recommend using that program if you need to change any presets?

BTW, Repetier uses Slic3r by default I think. It does not have its own slicer program.

Re: PrusaControl - official thread

Hi,

PrusaControl doesn't support MK2.5 (yet), but it's pretty cool so I would like to use it ever with my 2.5.
Can I use the Mk3 settings instead?

Re: PrusaControl - official thread

For MK2.5 always use MK2 settings 😉

It works fine, but is a multi-step procedure, and seems at odds with Prusa's "just hit print" paradigm.

Follow-up: Recent versions of Repetier-Host, along with recent versions of Prusa FW (3.1.0 +, that fix the dreaded M110 problem) work just fine. Slicer-PE is baked right into Repetier, and all the settings are there for MK3. (The only problem is Repetier-Server, which sends the printer into a reboot loop. But I don't use it, so that isn't important to me). So I'm a happy little printer again - damn that MK3 is good.

Re: PrusaControl - official thread

I've read this entire thread, but haven't seen the exact issues I'm encountering with PrusaControl (PC).

I've only printed out a few items on my MK3 so far, and PC has worked just fine. As a noob, I do my original modeling on TinkerCad (TC), which has also worked out fine... until today.

I designed a few simple maker coins on TC, saved them as STL files, and imported them to PC. My other TC models generated gcode and printed just fine, but PC really seems to hate these coin files, and I'm at a total loss as to why (they're really not that complicated).

One generated the gcode in a flash, but said the print time would be 1 min. and use about 0.1 m of filament. No way. Subsequent attempts (starting over on TC) had the same results.

Another seemed to generate correctly, but when I selected it to print off the SD card, the MK3 said the file was "incomplete".

A third seemed to generate ok, but when I printed it, it stopped on the fourth layer, and said the SD card had been removed (it hadn't, and wasn't loose). Then it asked me if I wanted to continue the print, to which I clicked "Yes", said it was heating, yet the hot end temp went steadily down while the bed remained at 60°.

A fourth seemed to generate ok, but when I progressed through the slices, I found it had not included the text on the coin, and only parts of other relief details (again, not that complicated or small).

Can anyone shed any light? Is it some inconsistent incompatibility with TinkerCad? Is it me?

I also tried to repair the model with Slic3r and then use PrusaControl but the result is the same.

There is an issue when slicing objects, which touch the bed with a very sharp edge. Then Slic3r slices that edge with the 1st layer and the resulting slice is so thin, that no extrusion fits. And that makes the 1st layer missing. There is yet another problem, where the brim is always printed at the 1st printed layer, which is the 2nd one in this case.

You may work around this problem by either printing the object over raft, or by cutting a bit of the bottom of the object using the Slic3r's "cut" function.

Re: PrusaControl - official thread

I encountered a weird problem with Prusa control. The program allows you to print on the build plate edges but the extruder assembly will start ramming itself against the x-axis assembly. Why is this happening?? I tried attaching a video below but the attachments panel won't allow me.

I'm using an I3 MK3

Re: PrusaControl - official thread

Are you using a brim? Could it be that the object fits on the build plate, but the brim or perimeter ring extend off the plate?

Re: PrusaControl - official thread

Problem/Bug with generating G Code.
My problem is that it stops at 21% when generating G code on a very simple model. But have no problem with larger and more difficult models...
The smal easy model is sliced just fine in Slic3r and Cura, its a 37 min print. the model is 40x60x7 mm.
Anyone have a Idea what to do?

Re: PrusaControl - official thread

I'm having an issue with PrusaControl on MacOS (Mojave) in so much as I slice an object and it gets to 100% and then just sits there and does nothing. I left it there for an hour and still no change.

Re: PrusaControl - official thread

UPDATE:

Hi guys,
PrusaControl is no longer developed and will be merged with the Slic3r PE. In case of issues with the prints, please use the latest Slic3r PE from https://www.prusa3d.com/drivers/

Re: PrusaControl - official thread

Is it possible in Prusa Control or Slic3r to get an idea of timings between colour changes?

I would like to know approx when I had to be around to change the filament.
