I did notice those on ebay and had seen that there was a driver for them. The price is very tempting. Especially since these are not mission critical or production machines. On 02/02/2017 04:27 AM, andy pugh wrote: > On 2 February 2017 at 02:35, dragon wrote: >> Are there

Re: [Emc-users] Wyse S30 terminal as a CNC computer?

Those are a bit under powered. Laptop IDE is very common in thin clients. I use a Wyse Rx0L thin client as my network file server. It is a bit more powerful and has 2xSATA onboard and 1 x laptop IDE. On my file server I use all three ports (plus one USB drive). It has performed faultlessly

Re: [Emc-users] VFD recommendations

I use mitsubishi VFDs particularly the e700 series. They use a rs-485 serial connection. I have a python program to communicate with them. I've also toyed with a Yaskawa drive with Classicladder over modbus. These are expensive drives to buy new, but can be found on Ebay. Just other options

Re: [Emc-users] Tida_TD-1336_lathe

Kirk, I forgot to mention that I read somewhere online that it is actually common for the back gears to get broken on these lathes. It comes from user error. There is a threaded pin on one of the spindle gears that you need to engage and disengage. If you keep it engaged while you have the

Re: [Emc-users] VFD recommendations - braking resistor vs mechanical brake.

Ed Fanta does rigid tapping on his CHNC. I don't believe that he has a breaking resistor on the VFD even. IIRC I watched the output of the SPINx1 and it just goes from a + voltage to a - voltage and does not "stop" he does have a fairly high line count BEI(?) encoder on the spindle. It works very

Re: [Emc-users] VFD recommendations - braking resistor vs mechanical brake.

The spindle brake is usually something that holds the spindle after stopping. I believe my Bridgeport has a ratchet which engages a gear. Obviously, I don't want to try to use that to bring the spindle to a stop. The reason you need a braking resistor is to dissipate the back emf from the
