Finally, up and running! An X2 stepper motor power feed using a PIC controller unit to move the table, 10 speeds and programmable limits. Video to come shortly: A few pics of my veroboard built circuit – not the neatest, but it works! The ArcEuro purchased 4amp stepper motor drivers sits inside the controller box [...]
I first started this in Dec 2009 and put it on the shelf for the last 6 months. I finally found the time to re-write the code, programe a PIC, buy a 4.2A Stepper Driver and give it a real test run in situ. Next – tidy the code, build a circuit and get it [...]
A bit of an update. I`ve been doing some updates to my mill at the moment but I`m hoping I should have some time over the next week to get a first simple prototype built. Quite a bit to do yet.
Well I got a bit further today. Managed to get hold of a Development board, load the PIC and test the circuit with an osciloscope. Here is the setup: EasyPIC5 dev board Osc, shows us when we are pulsing and is easier to test and calculate from than actually hooking up a motor. Although a [...]
Hi Guys After the sucess and enjoyment of converting my Vertex rotary table to CNC, I thought I`d jump back onto the X-axis conversion. I did try this some time ago and it failed so I didn`t post anything but now looking back, the two shafts were not aligned, only a fraction out but it [...]
