There are certain settings such as:
- P00.06 VF:Highest output Voltage
- P12.01 Rated Motor Voltage

Does anyone have experience adjusting these in order to drive a motor with the rated voltage...

If I am correct, the C program move commands do not know about max velocity and acceleration. I would need to program those myself. If this is the case, what would be a good way to do this? I noticed...

I would like to intercept M6 in KmotionCNC, and have kflop do the following:

1. Go to a certain point on Z axis (equivalent of a rapid move, if possible) and pause. I would then change the tool....

Thanks Tom. I figured that tuning the Gecko would be the way to go, and have proceeded as you suggested.
I noticed your demo of tuning a closed loop stepper system at this page. Would it be...

I have a Gecko G320 step/direction servo controller driving a DC servo motor with an encoder. I am using Kflop to provide step/dir output for G320 and also to get the encoder position. G320 has gain,...

My bad. It does not seem to be an issue with the drive. The source of the step/direction (kflop) seems to be doing something non-obvious to me.

Yes I did. The problem follows the G320. Thanks.

I have two G320 drives. One of them seems to be accelerating much slower than the other given the same step rate. The gain, damp and limit settings do not seem to affect the acceleration and...

I fixed it by doing a "recovery" upload and then "new version" upload. Will try your solution if it fails again. Thanks!

For some reason, I cannot see that any of my axis in KMotionCNC are enabled (it all worked fine earlier today). The pulse generators don't work either. All axis are enabled and both KMotion and...

I am moving, and unfortunately cannot deal with my machine shop... My machines are listed for sale at http://toronto.kijiji.ca/c-PostersOtherAds-W0QQUserIdZ28420421, if anyone in Toronto is...

I wonder if a dental piece like this would work as a toolpost grinder...

Oh, I just realized it only has a 3/32" shaft...

CalG, thanks for the reply.

I am little confused by your post. I do not have a VFD. The Yaskawa drive is a servo drive (SGDB). So, when you say VFD, I am not sure what you are referring to? Is...

I have got a 1.5KW Yaskawa drive that requires 3 phase power input. Is it possible and safe to run it off a rotary phase converter? Is there a better solution than RPC considering I do not have...

I also figured that running different series would not be possible.

How about using a big driver to drive a smaller motor from the same series? Are there any configuration settings that would...

Is there a Yaskawa motor compatibility chart or at least a guideline?

To what extent (if any) can Sigma I motors be used with Sigma II drives, or the other way around?

Can I use a large drive...

Yes, they are Angular Contact bearings. Both pairs.

I figured that the top bearing set needs to float. I think I will either leave them be in the slip-fit (in which case why not just use a...

I thought I did not lock the upper bearings (since I have that spring washer). But it seems that the washer will only help with shaft contraction, not expansion relative to the housing. I guess I...

As far as the meniscus effect goes... if one allows the mold to be higher than the top area of the flat surface (ie. not building a standard surface plate), then the sides of the mold near the top...

I got some precision duplex bearings on eBay and thought of trying to build my own spindle, following the footsteps of Jroque (thread: http://www.cnczone.com/forums/showthread.php?t=7004&page=7).

Jeff, the X axis is bolted to the base. I guess you are asking about the Y axis (the one holding the Z axis). That one is not supported on the other side. I wanted it to be able to engrave on the...

None of my family members was particularly impressed, so I decided I'd give it a shot here...

All three axes are THK KRxx elements. While not inexpensive (each of the KR elements can cost from...

I thought it was more on the order of 0.0003"/ft flatness. This post has more on the flatness: http://www.cnczone.com/forums/showthread.php?t=55625&page=2.

Also, I seriously doubt that a thin...

No. By inserts, I meant threaded inserts used to bolt the rails down.

Once you had the holes drilled, what did you use to fasten to the EG?

Bruno,

I also wanted to avoid the machining of EG block. The first idea that comes to one's mind is to use self leveling epoxy to create a flat surface to which the rails would attach. However,...

I have been thinking about using self leveling (table top) epoxy to get a flat surface for linear rails. I would like to have the inserts sit in the E/G mix held by a fixture above the surface....

What size mold should I make to make it convenient for you and allow for having 15mm diameter rocks?
Is it true that cutting such non-uniform material will not disrupt the strength in a way that we...

Cameron,

have you managed to get or make a larger fixture for your test machine? I am interested in making some samples for you to test, but the 2mm for largest aggregate size is a little bit...

I believe there are two types of people following this thread closely. The first one is the experimenters, the ones who contribute 80+% of all posts. They will keep trying to improve the mix even if...
