I'm very sorry I've been away from the masso forum for a long time. And have not been getting the emails. If anyone is interested I've been using it for more than a year now. I wired it like a proma THC 150 without the resistors. Tried it with them but it didn't work. The problem i was having is a hesitation at the m666 and m667 code. I have a very robust machine and I can change direction of movement without slowing down. So I run with the THC on all the time. I see there's a fix for that so we'll see if it works. I run this thing probably 10 hours a week and it rarely lets me down. Again I'm sorry for letting my people in the masso world down for the very late response
