There are 2 x 100nF capacitors across the signals to GND for noise reduction. If you don't have, just pull off the black plastic after soldering and bend the pins down.
The rotary connector can be a 4 way if you desire, I made an error here and assigned a 5 way for some stupid reason. Please ignore pin numbering in the connector layout picture (the black background), pin numbering on the CAD drawing is correct. Ensure this is level before fully soldering. The connector for the screen needs to be set off the board by the amount shown in the drawing. I find it easier to plug in the Arduino to align the connectors properly, soldering just pins at each end temporarily then unplug the Arduino and solder completely. I don't know why this connector is not on the standard 0.1" grid but the Arduino designers felt it nessesary for some strange reason. Mount the single row header connectors as shown in the drawing, the 10 way will need to have its pins bent slightly to align with the Arduino board. Push the new filament into the extruder, pushing against the end of the old filament and keep pushing until it is picked up by the sprocket and starts to drive itself.Ĭut a piece of double sided thru hole plated prototype board to 4'' x 2.1" (yes, imperial I'm sorry). The cutout for the screen may also need to be filed to fit, I did mine while the boards were assembled and screwed into the base so as to ensure alignment.Īs a side note, if this ever happens to you there is no need to stop the print.Ĭut off any bent end of the filament that is running out, get the new filament prepared by making a clean cut at the end, make sure it's straight for about 30mm. The holes may need to be drilled out for the screws, I found the holes in the lid just right to accept the screw and make their own threads. (I printed them seperately) See note below My case may look odd as I ran out of filament half way through printing the top. I set my Sli3er at 0.2mm layers and 30% infill.Įverything else can be left at your prefered settings. Temps were: bed at 65 deg (first layer only) and Hotend at 215 deg I used PLA filament, glass bed with autolevelling, and glue stick adhesive. The case can be printed in one go as the 2 parts will fit side by side on most printers. This project is about the design and building of a pendant. IF ANYONE OUT THERE CAN OFFER ASSISTANCE WITH THIS PLEASE LEAVE A MESSAGE.
Mach4 cnc controller board code#
I will admit I am stumpted with some of the code in Mach4 and I am unfamiliar with the Lua language. The errors would be in the PLC script code, Inputs 30 - 39. The Jog Step DRO changes in Mach4 screen but does not actually seem to change the Jog Rate itself. The Pendant works fine and sends the appropriate keystrokes to Mach4, (CTRL1 - CTRL 0). SPECIFICALLY THE JOG STEP SIZE SELECTION. TESTING UNCOVERED ERRORS IN THE CODE IN MACH4.
If someone knows a way to 'output' axis coords to a HID device via USB please let me know. The only shortcoming with this method is it's one way, there is no communication from the computer back to the Pendant, so actual machine coordinates are not available. I did it one key at a time.Īn Arduino can be programed to send keystrokes but not all Arduinos have HID (human Interface Device) capabilities, the Leonardo and the Due being able. Sounds complicated but once you get your head around how all this works it's fairly simple. We can 'send' keystrokes to a Mach4 'Input', have it intercepted by the keyboard plugin and through a PLC script, perform an action.
The keyboard plugin allows you to configure shortcuts on the keyboard to perform actions, just like most software. The idea to use the keyboard plugin came from a similar instructable here on Instructables but was incomplete and would never work without a lot more research and work something I have done and present here. Luckily Mach4 comes with some plugins, one of which is the keyboard plugin. I have a XHC motion controller which is excellent but does not cater for a pendant. There is just nothing available at a reasonable cost and the units that are available need particular motion controllers. It allows you to control your machine at the machine instead of at the computer keyboard. One very useful add-on device for a CNC machine is a MPG or Pendant. It is CNC control software.īecause Mach4 is newish there is not too many add-on devices for it.

Mach4 is a fairly new piece of software by New Fangled Solutions.
