I just finished compiling a branch of Marlin 1.1.9 for the Pulse XE. Im still working on getting my Z-Offset set and after I get some prints I was going to publish the source code on GitHub.

Its not super hard. The printer itself is just a variation of the i3 design.

I did this becuase I wanted the Pulse to be a more stand alone printer and not be forced to use MatterControl. I like MatterControl for some of the things it can do, but for slicing, I feel like i can get better prints and have more control from Cura or other slicers.

So I tried un-installing and re-installing MatterControl and creating a new profile.

None of that worked.

What I did find was that my Repitier server was running on startup. When I killed that service via the Task Manager, I was then able to connect Pulse to MatterControl.

So, I think killing the server process made it work.

My printer hasnt been used in a few months due to being busy with life.

I go back to it and try to connect it to MatterControl and it will not connect.

I plug the Pulse into my computer and the computer recognizes the printer and assigns it Com4.

I go to MatterControl and click connect.

I follow the steps (making sure that the printer is not connected when it says that and connecting it when it says to).

When I get to the step that it connects to the printer, i usually get the red error text saying that MatterControl cannot connect to the printer.

IF i dont get that error, it gets stuck in an Attempting to Connect state.

I have tried to do it manually and selected the correct port and again, it gets stuck in 'Attempting to Connect'

I have let it run for 20 minutes and more and it still didnt connect to the printer.

Any suggestions?

So Joel Telling, aka The 3d Printing Nerd, had this exact issue.

Here is his video: https://www.youtube.com/watch?v=OOV91Egw3XE&t=2s

His 'fix' was to flip the c-clips over.

Bondtech also has .stl files of clips that you can print and use to replace the ones you have.

What all did you enable in the firmware? And, if you are using it with a Pulse XE, would you be willing to share you firmware?

I've been talking with MatterHackers support and they sent me some starting G-Code that you can use assuming you have a 'D' model Pulse. (I think the sticker is on the back of the gantry with the model number)

I have not yet had a chance to test it yet, but this is what they sent:

G28 ; home all axes
M280 P0 S160 ; clear probe status
M280 P0 S10 ; deploy probe
G29 ; run firmware mesh leveling
M280 P0 S90 ; retract probe
G1 X15 Y10 Z0.8 F1800 ; move to front corner of bed
G92 E0 ; reset extruder position
G1 X100 Z0.3 E20 F900 ; purge hot end
G92 E0 ; reset extruder position
G1 E-2 F3600 ; retract filament

You can change or delete anything after "M280 P0 S90" if you don't want to use the purge line.

Since Marlin has the ability to doing a bed level routine and save the data to EEPROM, is it possible to reflash/update the firmware for the Pulse so that this can be done?

@larsbrubaker said in Blob at end of print:

still having this problem on the alpha buil

ill test it this weekend and let you know

Sure thing, its not a brand new PC, but I have no issues running very heavy software on it (Siemens NX, PTC Creo).

Operating System: Windows 7 64 bit
Processor: Intel Core i7 3630QM CPU @ 2.40 GHZ
Installed Ram: 12.0 GB
GPU: NVIDIA Quadro K2100M

MatterControl seems to take FOREVER and regularly consume 5-6GB of Memory to slice models.

For comparison.

In Cura 2.4, I can slice a benchy in under 15 seconds and be ready to put the G-Code on a SD card and print. In doing so, consuming less then 500 Kb of memory

In MatterControl 2.0.0.10065, the same benchy with standard settings takes 58 seconds and consumed 1GB of memory.

Thats a 4x increase in time. I can compare more models if you would like...
