Sure, that seems perfectly doable. Remember, if you're directly controlling the stepper, you're on the hook for things like acceleration (real...
With a Raspi, you could output step/dir pulse trains directly from the I/O header. With a PC, you either have to be able to physically install and...
Sounds like you have a fairly specific setup then. I don't believe it's considered good practice, generally speaking, to use G53/G28 machine...
Use your range of work coords- G54, 55, 56, etc.
Pulse length isn't (specifically) changed at compile time, which is where defaults.h would come in. With a vanilla grbl hex installed on the...
Assuming the painting is taller than the TV setup: One of these:...
Wiring is the worst part of machine-building! Hahaha. This thing's looking great, I've been watching it come together. :thumbsup:
I've never seen one without a flange, in all my research. If they do exist, they probably won't be the cheap C7s made en masse, they'll be...
From a machinist/metrology perspective: Parallel Y: lock one side up with your cross-braces and make sure the V-wheels are nice and tight. On the...
Looks like a ton of backlash to me. The straight lines are where the y axis is moving before the x axis has "re-caught" its lead nut. Hmm,...
As an open platform, converting it to screws shouldn't be enormously expensive or complex. Not great for something sold as ready-to-run, I know,...
Oh, gotcha. So you'll be in PncConf too. There's a little trickiness to getting the card up and running, but once it is, it should all be the...
I wonder if that 100.3mm is statistical noise or not, because that's the direction I had expected it to go with more torque capacity. The...
Since all motors and leadscrews are slightly different, no two scales are gonna be identical, even if someone had a HAL file ready to go. Setting...
A belt-driven 1500mm machine is a near-zero-force laser platform, not a milling platform, but all the flex in the world doesn't adequately explain...
An easy way of swapping drivers (for a 4-way test: 2 motors, 2 drivers) without having to rewire anything except plugging motors is just to rotate...
No, you'd just change your calibration for that axis. Your steps per mm would be 4x fewer, more or less. You can set your microstepping to...
Struggling to come up with a reason for 1000mm to be accurate, 400mm to be high, and 100mm to be low. Seems impossible from either a motion...
CNC is often, unfortunately, more difficult and technically demanding than a lot of these maker websites suggest. Considering the price of these...
Simple and old-school would be Mach 4 and an Ethernet Smoothstepper, I suspect, or something along those lines. You could probably go Mach 3 and a...
