 Installed the latest version of Mach and then worked with the reverse and high and Dir and now the machine has all the axis moving in the correct direction thanks for the help now it's on to the next battle so many I'll have to choose one think I'll go for the limit and home switches next that sounds like a good one.

Chip & RC
Tried switching the active low and high same thing no change. Chip just downloaded latest version of Mach I'll see what that dose man it's just crazy what it's doing yup it's always something throwing a wrench in the works.
 Hey one more thing has any work been done on LC for the lathe still waiting for that to get fixed.

Hi guy's Happy New Year to all
Well after having some issues with my new drives i have my machine back to together again and running so i guess it's one fight after another until the jobs done so on to the next fight. The machine responds to Mach but the travel is in the wrong direction meaning the drives work reverse simple enough right just go into home and limits and change the direction well i did that and no change so i shut down Mach and rebooted the computer no change same direction tried this several time before i posted this here any ideas as to what could be the problem as always i am indebted to you all for the help my thanks.

Thanks Chip
 Would there be a schematic to connect the printer cable to the Gecko drives as well somewhere.

Hi Guy's
Well i am about to try and connect one drive to my milling machine some where i had seen a connection pin out but can not find now can anyone point in that direction please.

No what i have is the original drives in the machine they are analog SD drives really massive drives and they maybe in good order don't know for sure they are servo drives in going through the machine i found that one of the power supplies is bad giving a high Voltage on the - side to the drives the drives did have a fault indicator on for voltage but in calling Servo dynamics they said that the drives if need be could be repaired but the cost to repair them would exceed the price of a new drive so mythought then is just get new drives to start with my problem is finding a drive that i can afford for this project the ones i have found so they are rated high enough for my power supply and motor's but when contacted say don't run these drives for my machine as they won't handle the motor's.

I have talked with Gecko and they rate there drives at 80 VDC but they can handle a Max of 95 so to me if a manufacture advertise that there drives are 100 VDC then they should be able to handle more then that or advertise that's the MAX not the operating Voltage.

Hi Guy's
 Help me to understand this one a company offers drives that they advertise @ 100 VDC and 20 Amps but then say not to run them at the advertised rating ( HUH ) how's this work.

Hi guy's
Made some progress sorting the machine out i found a small power supply that supplies the 15 +& - voltage to the drives has a voltage reading of 15volts + and then a Reading of 27.8 volts - so this must be down as i see it would it be possible to use a 12 volt power supply from a computer as it has + & - 12 volts ? next i have traced back the wiring for the servo motors to the wiring cabinet so now i can power the motors from the cabinet wiring removed all the drive boards and gave them a look saw nothing smoked so i am hoping they a salvageable and in looking at the wiring from the drives i see only one wire that looks like it is capable of handling the current to the motors the others are way to thin so the big question is how dose the drives reverse the power to motors is there another devise that dose this?
