Please see files section of RELS data. I will be sending wiring schematics and photos at a later date. The arduino file is my current file, although there are more BETA version if required. The

Hi Tamara. Nice to hear from you. Yes I produced all the STL files based on a pdf drawing that was included in the original wooden laser cut model. A lot of hours to convert to CAD, some 60 parts to

John, I don't have that many colors of filament print.? Did you create all the STL files? I have an Elegoo Resin and SeeMeCNC Boss Delta filament printers. Tamra

Changed the cover photo. I drafted and 3D printed a harley Davidson bike, approx 250 mm long. I have all the STL files and assembly sheets available. Just let me know Thanks John owner. -- John

Yes still alive and kicking, sorry for the absence, blame Covid, it gets the blame for all the topsy turvy world we all live in currently. Anyway, I will try and invigorate this forum, naturally with

Hi Ralph, good point although I suspect it's going to be a pain to assemble frequently.? Your suggestion does however spark the thought of sacrificial panels that could be easily changed. Mike, not

??? ??? Not to suggest more work , looks like you have a plan here .? I found this a couple of years back & it's on the list to add to my newer to me lathe at some stage hopefully sooner than

Julian, I would not worry about chips melting into the plastic. If you ge an accumulation just print a new cover. Ralph

Quick sitrep for those interested. Electronically ... With Marks help, things have progressed well, with one small issue.? For the X axis I chose a caliper that displayed to a resolution of 5

I took those diagrams to be external to the caliper if required.? Anyway running off the same power supply (in the test the usb from a laptop because I needed the connection to run the serial

After looking at the image, the REQ pin has an internal pullup (typical 100k, range 70k to 140k) to 1.55v. That would mean that the 3.3v supply of the Arduino would pull up very close to 3.3v. Current

John D Nice print work ? John L

Batteries look really good, John. i'd never have thought of making my own ... respect! Mike, for the X axis I'm not using a scale typically as in John's second photo.? I'm intending to dismantle a

??? ??? Julian , I just saw the pic of your connector , what scale are you using that has 5 pins ? ??? ??? thanks ??? ??? animal

You might find this photo interesting too. The calipers really don't like the power supply a long way from the unit. Tends to result in noisy readings even when powered from that plug in cable.

That's a rather elegant design, John.? Perhaps I should have checked Thingiverse before I made my version. Mine was only ever going to be a temporary item though.? The finished version will be

Hi Julian. Well done, send as many photos as possible please John

Hi Gene, I found that site a while back, very useful.? The calipers they show are the very cheap ones which, I believe, have a different output format and are usually 1.5v.? The caliper I'm

Hey Julian, Are you planning to keep using the battery in the caliper? Wouldn't it be possible to hook up power from Arduino to supply the caliper with power, getting rid of the battery? A fresh 3 V
