Hi guys,
I'm lost and appologize for the long post. I have rebuilt a lagun milling machine with mach3, akz250 usb motion card, and viper tune STEP2Linear with great success. I have built a small...

Hi.Hope everyone is well. I have explored cad/cam software to try my new set up. I have found that I have some imprecision due to a bit of backlash in the screws and I am getting a bit of jerking is...

You are right it does say that and i don't know why. My breakout board has 15 inputs and I use successfully 13 of them. Both x and y (i2 and 3) home perfectly, i also use input 6 to 11 with the...

Hi Gerry,
Yeah....I know it sounds like that and yet I know my pin is set. That being said, the del (on the breakout board) is indicating when the home switch closes but it does not mean that the...

Thanks Ben,
I understand. Larry from Viperservo is also saying that us digital is a better product. Since I am a new at cnc conversion and trying a fairly new product from Viperservos to convert...

Hi guys,
My Z axis will not home. When all ref is pressed I can see that the z axis icon becomes green without moving the motor (it does not zero machine coords either although automatic zero is...

First aluminium chips last night! And it went very well.
I am using the cheaper version encoder AMT 102 or 103 I can't remember (single ended anyway). The motors vibrate a little bit when on...

Hello, I gave up for now on converting my linear encoders. I got it to the point where it seems to give me square waves but since I don't have a oscilloscope it was hard to see if the circuit was...

Hi,
it turns out that my linear Heidenhain are producing a small voltage at the diodes: it swings from +360 to -360mV. As per our discussion, i modified your sketch with a simple voltage divider at...

Hello Again,
Thanks for the quick reply. I used a Futureshop Dynex usb to rs232 converter and it worked like a charm on my first attempt. It seems to be able to detect the baud rate on its own has...

Hello,
Here are some questions following my very first try...
1-Can a usb to serial converter be used to communicate with the step2linear card via vipertune?
2-I have 15.4V at the step2linear...

Hi
Congratulations! I noticed on Viperservo.com that your step2linear cards were ready. I ordered 3 of them! I will let you know how it turns out! Thanks for all the help. Eric

Hello! Thanks for the input! You are right about the Heidenhain scale putting out very little amps...11uA. I ll get started on your suggestion and keep you updated. Thanks again!
Eric

Thanks! That looks relatively simple and I think I already have some 393 at home!
I also found this on internet. The circuit is interesting since it amplifies the signal too. The 4069 hex...

Hello again,
I found some information on my linear encoders. Do you think those will be compatible with your card? Thanks.

Hi Larry,
Would it work open loop or you think that the pwm "translation" to +/-10V will not be precise enough? You mentioned very little backlash to none...from your experience, what will be the...

Hi,
The mill is a lagun 3v model and comes with linear encoder that were used by the heidenhain tnc155. This controller is damaged and I just can't see spending money to fix it. I'm able to move...
