Re: z axis randomly plunges too deep

What feed and seek rates are you using? It's been a common thing for the Z axis to miss steps when retracted faster than 250-300 mm/m. On a big retraction at seek (G0) speeds, it can bind up dramatically; but most of the time, the under-retraction is not immediately noticeable. Depending on the cont...

Re: Heeks CNC .xml

I'm not sure exactly what xml file you are talking about. When you post process and save an NC file, that file (no matter what extension you give it) is a simple text file containing lines of GCode. Controller software should be able to read it, though... In the Output window in HeeksCNC, it should ...

Re: Blendercam and Shapeoko Anyone doing this?

I'm afraid that I've only had the same, not-great introductory experience with BlenderCAM. I haven't been motivated to push through the learning phase because my current FreeCAD --> STEP file --> HeeksCNC --> G-Code toolchain has been working for me. I think I checked out Blender/BlenderCAM when try...

Re: Conventional vs climb. When to use what?

From CNC Cookbook: Climb vs Conventional Milling Consider Conventional Milling When Micromachining For all the same reasons, but considering deflection is much worse micro-milling, you should prefer conventional over climb milling most of the time when micro-milling. And from CNC Cookbook: Climb Mil...

Re: Edward's S2 Enclosure

I don't think you'll have much of an issue with resonance as long as the panels are solidly secured. i.e. If they're slid into the extrusion channels and fit loosely, they might rattle around, but if it's all connected well, it's the mass of the entire structure that's resisting the vibrations. Sinc...

Re: HeeksCNC 1.0

There's also a (not-new) issue if you mix attached and non-attached operations. It's not subtle, the post-processing will blow up.

If you're compiling the project yourself, adding the following line to Program.cpp at line 887 or 898 will fix the issue:

Code: Select all

				theApp.m_attached_to_surface = NULL;

Re: HeeksCNC 1.0

The retraction between step-downs is expected in HeeksCNC-generated toolpaths. The keep tool down setting looks like it's talking about between curves in a given pocketing operation. The bug causing a hole to get drilled into the starting point for 3D zig-zag operations is still there. The rapid ope...

Re: soundproofing enclosures?

I haven't made any official readings but this thing is very quiet, I kinda wish I had of purchased this before attempting to make a soundproof box. While this thread's focus is soundproofing, an enclosure can help manage sawdust and other debris. So, don't feel too much regret! I since learned/real...

Re: Edward's S2 Enclosure

I'm still going to use bubble-wrap under the equipment, but the rubber washers just made me think of the screws and rubber washers I've seen in hard drive mounts in quiet PC cases. The screws contact the threads, but all contact with the metal on the other side is buffered by rubber washers and grom...
