Trying to figure out how they expect to get TTL through that third pin with a 12V power supply! Unless you're supposed to also feed the Arduino...
Looks like some kind of JST connector, and I'm not sure. Let's see a close-up pic of the board, all the pins are labelled. Can't send a signal...
Lots of progress made! Gonna try and show what ended up being a fairly complex, non-linear process as quickly and simply as possible. Obviously if...
Those are good prices! Looks like they have USPS shipping options as well, which would put them at a really good price point, albeit perhaps at a...
I just tested- $15 in US UPS shipping for three motors puts it above the Amazon price, even with a 3+ volume discount on the motors. Other...
I do recommend the STEPPERONLINE motors, for anyone who needs any in a hurry while they're waiting. Nicely-packed, with good literature, at very...
Yep, that's it. You'll have to manually remember to set laser mode on and off when switching tool, in the serial terminal.
Weekend Update! Got the head off, interesting two-part lead nut assembly, which I'm going to replicate for the ball screw assembly because it's...
I started with a machine lathe, because I knew I could make essentially any part of any machine with it and it would help me internalize the...
Things got a little carried away here. I was only intending to take a poke around at the saddle and take some measurements... [ATTACH] 1204...
Sounds like my wife's house projects! Yep! TIG. The round was turned top and bottom, and then the plate was bored and turned on the front side to...
You don't have a stray ground somewhere through the machine? Seems more likely than noise coming from a shielded board.
Ha! Let's not get too carried away, I'm between two months and two years behind schedule depending on which project you're looking at! :ROFL: But...
Making a laser diode housing that could fit into a spindle collet could be a solid option, that I've been pondering on for machine #3 which will...
Another relatively minor update, squeezing a little bit of mill conversion work in between other jobs and projects. Soon this is gonna be the main...
Oh, the plate? You hadn't said plate. Yeah, you may just need more wheels/surface area. Could you add a second Mini Gantry Plate on the back of...
Wasn't really sure what the mini gantry thing was about. I was referring to the gantry (x-axis) in terms of the plates to make the quasi-C-Beam.
You could get away with some simple 2060s for the columns if you had some nice beefy plates to mount them to the sides of the base. You could skip...
Most obvious option: is the direction wire from the microcontroller pin all the way to the stepper drivers properly wired and testing for...
While they're on, they should also carry OD3+ laser shielding acrylic. Seems like JTech Photonics is the only place on the internet to get it?!
