Re: [Emc-users] Home switches.

Home switches should go to the positive side , z up, y towards you and x on the right. Most 4 axis I have used were mounted on the negative end ( left ) ( mazak) but the carousel was not in the path of the 4th axis, the fadals ( which homed to the center of the table , as well as the daewoo) were

Re: [Emc-users] 7i90 not listed in pnc

Ok, I got this all loaded , got some help from Peter and am able to drop these pins to ground and watch encoder raw count show pin activity. So , great everything works, very Happy. The bad I think I reverse biased this led and popped it. I have another encoder and motor to try to read counts

Halmeter has blanked fields and inoperable buttons, so I cannot select pins. Halscope shows no active threads. So I cannot continue as the Hal tutorial shows. nothread.jpg

Re: [Emc-users] 7i90 not listed in pnc

Pin 1 and 3 are my a and b from the 7i42. I have verified encoder is operational and 4.56 volts at pins 1&2 on 7i42 so all seems good there. I'm pretty sure this is a syntax problem . Input ? hal.jpg

Re: [Emc-users] 7i90 not listed in pnc

7i42 in hand, 7i90 configuration built. Linuxcnc starts, and no real time error , that's awesome. 50 pin cables and connectors assembled. All hooked up, all power on. Mesaflash readhm2id gives all pins and their assignment. So I presume that is all as it should be. I printed a copy if this

[Emc-users] Encoders

Hi all. These ametek motors have undefined encoders on them. One is just an empty 4 pin. The other has a flat 4 pin ribbon. I'm awaiting my 7i42 . The flat ribbon is marked with a hot lead. I also have a 5v current limited supply on order. I'm thinking set voltage low and shuffle ground until I

I have no experience, I do have a next victim for conversion, a 10*50 comet knee mill. It has Sony scales on it , I will attempt to read them with this message card once I get there, if they prove good I'm going to try a pair of these , eBay item number 322393653446 The beauty of it is it closes
