There will be a minimum frequency setting within the *VFD* somewhere that is causing this.
That wasn't the setup in the F360 file that you posted. Again, if you're setting your machine zero using the edge of the stock for this sort of...
You're setting your zero off the fixture at the moment, aren't you? Exaggerating: Suppose your fixture is actually 6" wide, rather than the 7"...
On the machine? No.
That's the way to do it. Good in theory, but not necessarily in practice - F360 is putting the centre of the part at 3.5" from the origin (being...
That will only work if your fixture is also *exactly* 7.000 inches wide in real life - any error between what you tell F360 that it measures and...
What are you calling the fixture? Are you zeroing X & Y, or just Z? Chance are that there is a (small) discrepancy in the position of your...
Yes: You won't be able to pre-load the bearings in the double row against each other to remove axial play (been there / done that!). Matched sets...
Hi, Just to say a VFD only works with an AC motor. You would need a VFD or DC motor drive (depending on your choice of motor) that accepts...
Just a thought: are you using the same computer for all of the tests?
If it isn't you pressing those buttons (or if they aren't connected), it sounds like a classic case of EMI. docs:blackbox-4x:faq-emi [OpenBuilds...
Sounds like something in your Adruino IDE project setup - a grbl.h file is included in the zip download.
Machine coordinate origin is always top/back/right (for a moving gantry machine) All machine coordinates are negative relative to this. I'm...
No, I think you've misunderstood. If you're using Openbuilds Control, you can set the active Work Coordinate System (WCS) in the DRO at the top...
You can change the WCS origin ("zero point") using the G10 L2 [...] command: G-Codes Remember that you will need to set it back again if you...
G Code looks OK to me. It still smacks of something loose, but your workpiece is pretty substantial, so I doubt it's that that is flexing. Is the...
How are you holding the workpiece down?
It's a reminder that no matter how rigid we think something is, there is always a certain amount of flex - even within the tool itself. The...
Thanks very much for the feedback, and glad it's working OK for you :) I'm not actively working on it at the moment as it suits my needs, but:...
Did you transfer the maximum speed and (importantly) acceleration settings for X, Y and Z from the old controller to the new? Even if you did,...
