CNC adapter PCA is for sale! 25 Euro including shipping. • Documentation links of the PCA can be found at the bottom of this description. Please send me an email when you're interested: [email protected]. • -------------------------------------------------------------------------------- • This D.I.Y. CNC system is made out of many • re-used parts and pieces. • The video is a timelapse of all the work done, • I don't claim the rights of the music, it is just • there to block some of the noise of the machine. • • It is controlled with DeskCNC, has 3 (modified) • UHU-servo drives and a power/safety unit mounted • underneath the base plate. • The electronics ensure safe operation, and also • provide diagnostic information in case of errors. • It is (since 1998) the forth version I made, but the • first one which is able to manufacture usable parts. • The earlyer versions where based on stepper • motors which could not really handle the bulky • mechanics. • As an electronic engineer, the mechanical part is • usually the most difficult piece. Luckily my uncle • helped me out a lot with valuable advice and many • many weekends preparing the so needed • mechanical parts required to mount sensors, • motors etc. • • The accuracy for X and Y is approx 3uM per step, • and for Z 0.5uM per step. • Ofcource I have to add some mechanical • tolerances, but it is much more than enough to • make small PCB boards, front panels, toys etc. • The speed is set to a low safe value, but can be • increased till 375mm/sec! Even at these speeds • the amplifiers and DeskCNC controller keep track. • • On most of the CNC forums available, I often found • that people are strugling to get a good start on • (mainly) the electronic part of converting a milling • machine into a PC controlled CNC system. • One of my colleagues is facing the same issue, so • I decided to design a 160 x 100 mm Eurocard pcb • board which will function as a adapter board for the • DeskCNC controller, and will interface with the • sensors, motor drivers, LED's etc. • • (It is basically a plug play board with all • nececarry connections to easily convert any • milling machine into a CNC system. Even if you • have little electronic experience) • • Specification in short: • • Interfaces all machine sensors (END, HOME, • Emergency-STOP etc.) • Provides safe low voltage power for sensors, • LED's and DeskCNC PCA • Runs on any voltage 110V AC...240 AC • (or external 12V,) • Povides accurate diagnostics on sensor • status, hardware errors etc. • Should fit 99.9% of all milling machine • conversions to CNC systems. • Safe to use. • All in/outputs are buffered to withstand • shorts or wiring errors. • • I hope to have it ready somewhere in April, if • any of you is interested, just let me now. • I come back to lt later. • • Regards, • J • • Email: [email protected] • • Documentation links: • • -------------------------------------------------------------------------------- • CNC adapter PCA: • http://www.keepandshare.com/doc/20637... • • http://www.keepandshare.com/doc/20637... • • http://www.keepandshare.com/doc/20637... • • http://www.keepandshare.com/doc/20637... • • http://www.keepandshare.com/doc/20637... • --------------------------------------------------------------------------------
