Not my favourite material, but here's my $0.02: Just keep the swarf clear or there will be a spaghetti ball you will regret making. Lower the spindle speed, take deeper cuts than normal and pull the swarf away often. If you need a lube, try Johnson's Baby Oil, it works well on plastics and...

My PIC18F877 controller died. It used a WinDoze UI which refuses to run on Win10 or 11, and anyway I no longer have a Microchip programmer to fix things.... so it is joining more old windows stuff heading to the junk bin soon. The Teensy and the new Espressiv chips are light years ahead of the...

As someone who makes A LOT of smd boards, may I offer two suggestions which will make this a whole lot easier for those doing this for the first time... 1) buy a stencil. That makes the solder paste placement extremely easy, and accurate. The board manufacturer will supply those for a small...

Trade for some M8 taps? :)

The drill as you would expect, is very hard and brittle. A mag drill would be needed to apply high pressure and slow speed. And flooded with a good lubricant. Slow is the key point - this drill produces tiny chips (like an end mill) so it is very prone to chatter.

HiRoc drill will cut through that like butter. Just take the time to learn how to use one first. https://www.kbctools.ca/itemdetail/5-100-20340 HiRoc drill

Looking at the MachTech documentation - that is a 5V device. It produces a 0-5v TTL signal. docs: >> 4. Why would I need the VFD Filter? Sometimes machines that have a VFD or other frequency drive motor controller create a noisy electrical environment. This is similar to static on a radio when...

Are you asking for a circuit diagram? Or a PCB board layout? Is this single phase power or three phase?

Have you tried Sketchup? That is probably more suited to Architecture and cabinet work. Theres no reason why F360 couldn't do the job using a subassembly approach, e.g. constructing a wall panel or a truss. Buildings are not my expertise though.

Cool project!

No longer! I taught Digital Manufacturing at UFV. Engineering design, 3D CAD, materials, CNC operations, 3DP, metrology, etc.

Make a sub assembly with the pistons, cranks and rods: Activate the top level component. Create a NEW empty component called piston assembly. Add the pistons, rods and crankshaft which have been modelled either inside the design or an externally linked component. Add the joint relationships...

This is a simple design with three trays and an external reference to the mounting frame component. Each tray is a separate component, self contained with a body derived from a sketch The Mounting Frame component is a subassembly. This was a separate model which also contains two sketches and...
