Hi all,
Unfortunatly I didn't read this article befor buying XHC card(s). I have two MK4 M4 and Mk4 M3.
Generally this cards a running under Mach4 (Plugin ver. 5.10.2) also with Mach4GUI but not good enough. Firs installation, following instruction was not good at all. After reinstalling Mach4 and putting just plugin files into plugin folder, the Mach4 recognize the card and the movement was possible. But....
Btw. it's true, as Peter described, by working in mm, any go to config will switch Mach4 in inch mode. Tit' not neccessery to restart Mach4, but you have to execute G21 from MDI. It will be nice if Mach4 will stay in metric mode, but this is just nice to have, because when all is configured, there is no need to go in config any time....
Back to XHC. I cannot say what this card is able to do, because I know that backlash compensation is not at all implemented and this was NO GO for me. One of my machines is an old one, and has backlash about 0.1 mm what's far too much. I can put what I want in backlash compensation field in Mach4, nothing happens.
My expirience with support is bad. Also my disput was declined without any word of explanation but OK I took this as a learn-money. So this story is finished for me. On my old machine I take PlanetCNC again (this car has his own SW, no Mach4 is possible!) and for new machine I ordered Vital System Hicon Integra. Yes, Integra is expensive, I agree, but my time is also expensive for me ;-) On the end XHC was very expencive! 200 bugs for one card, two days of trying to run this card properly, several mails on 'support', then again deinstallation etc. So, if someone wants to have this two cards, I will give it for free (just transport have to be payed), but I cannot recommend it. Add a bit more money, and buy one of the cards the people here can recommend!
