Matterhackers Pulse XE Printer - printer profile questions

Posted · Matterhackers Pulse XE Printer - printer profile questions

Hello,

 

I recently purchased a Matterhackers Pulse XE.  It's an upgrade from my previous Monoprice.  It was nice that there was a Monoprice definition included in Cura, but there isn't for the Pulse XE.  So I wrote one.

 

It's probably still overly complicated and I'm still working out the kinks.  I still have to do some more testing.  But I'll happily share once its tested.

 

You can get the Pulse XE with an E3D lite extruder or an E3D V6 extruder.  I wrote  (started to write) definitions for both.  The problem is that the definitions are essentially the same, I don't see a place to capture that the V6 can handle hotter temperatures than the lite.

 

Question 1: Shouldn't that temperature capability be in the extruder definition?  Where is it located?

 

Question 2: I wrote definitions for both extruders, but I don't know how to define a way to allow a selection of which extruder is attached.  It seems to mostly be how many extruders are attached.  How do I fix that?

 

This one seems less likely to be captured and something I'm not as worried about, but;  the extruders can have different nozzles on them (regular culprits) -  brass, hardened steel, ruby - which really changes the durability for some filaments.  If there is a place that should be captured, I'll add it, but I didn't see anything like that.  I did understand that I could do material exclusion lists.  (I doubt I will write 6 extruder definitions (v6 & lite vs brass, steel, and ruby) and then build exclusion lists from that.)

 

Question 3:   Is there a way to handle different nozzles other than material exclusion lists?

 

Question 4: The printhead silhouette - should I be looking at the print head from the X-axis or the Y-axis?  Those are different silhouettes.

 

Question 5: If in the printhead silhouette the nozzle is the origin, what is the positive/negative X and positive/negative Y directions?

 

While I still prefer Cura as a tool, the mattercontrol print manager does autoleveling during the print; rewriting some of the g-code commands and breaking them into different Z heights while printing.  That produces a better print than cura currently does without printing through mattercontrol.  The Pulse XE doesn't really have a way to level the bed other than with software.  I've added in the 

M420

into the initialization code with a valid matrix in the firmware but that doesn't work nearly as well as the mattercontrol tweaking the g-code as it prints.  I assume that cura isn't going to adopt something crazy like this?

    Question 4 & 5: 

    It's like the Cura build plate.  Xmin is left, Ymin is rear, Xmax is right, and Ymax is towards the front.  Gantry height is from the bed to the bottom of the X beam.  I have a 5015 mounted on the right side of my print head and a baffle over the hot end fan intake so my Xmin = -32, Ymin = -32, Xmax = 45, Ymax = 50.  The silhouette of the print head needs only be that portion below gantry height.

    The dimensions are used when printing "One at a Time".

    Thanks @GregValiant, that's helpful.  Do you happen to know if those positive/negative directions are sensitive to

    'machine_endstop_positive_direction_x' and 'machine_endstop_positive_direction_y' settings?

    Those indicate the placement of the stop switches on the printer.  I'm not sure but I think they are booleans.  The full list of keywords and descriptions was prepared by Ahoeben of FieldOfView and can be found HERE.
