Re: [Emc-users] slo-syn drivers

Thanks for the help so far, and here is more info. If the parallel port is not putting out BTW 4 and 5v, I do not understand how to increase this. I am running the OPTO off the USB 5v supply. The parallel port, USB and motor supply ground are all tied together. The USB 5v is tied to OPTO. P

Re: [Emc-users] the Intel D510MO problem (and an apology to Don Stanley, et al.)

Thanks to a bunch of loaned parts--D510MO from Kent, Pico PPMC from Stuart, and Mesa 7i43 from Seb--I was able to get them working together. The solution--to look for the parport extended configuration register where it is likely to be--is more in the vein of a workaround than a fix, but it does g

Re: [Emc-users] slo-syn drivers

Thanks for all the replies, I tried the direct switch method to test the driver. I found my direction pin was not able to change state using the output from the parallel port, but expected a full 5v to change direction. Thanks for all the advice, and now I'm off to work on my 5 axis machine no

[Emc-users] Arduino EMC pendant, phase II

Thanks to help from people on the list and IRC, my pendant/MPG project has continued to make progress. This video shows the Arduino interfaced to a 25-key matrix keypad as well as the encoder and LCD from the last round. The board seems capable of handling it well though I did slow the DRO update r
