I don't have distance to go enabled, I will give that a try and see what it says.
I am running centroid cnc10 IIRC.
This is the engraving:
N21608 ;4th Axis Engraving
N21610 G0 Z4.
N21612 G0 X17. Y0.
N21614 T1 M06
N21616 S6000 M3
N21618 G1 X0. Y0. F2286.
N21620 G43 Z37.027 H1
N21622 A60.F2286
N26 is a tool change position. And all of the code is being output by the CAM software. Direction changes for the rotary axis are indicated with a - or the absence of a negative in the post. There...
I don't have locks on my rotary axis so I am limited to light cuts.
As far as the problem goes it only affected the one 4th axis op. If I skipped that op, the indexed ops worked fine and the...
finally getting around to using my 4th axis and cutting my first part. I think my problem lies in my post processor editor for my CAM software but while I am waiting to hear back from support I...
Thanks Al, as always!
So I am doing my research as I get going on my project and I am trying to figure out if I need to protect the servo amps from back emf. The drives have shunt regulators which shunt the BEMF to the...
Yeah, microns isn't an issue with this machine. It is a Smithy machine that I am trying to make into a useful lathe. I found a 14mm NSK ballscrew on ebay brand new in the package which I won for $79...
I am leaning towards the Pico system stuff to minimize integration. I just spent some time reading over on the Linux forum and Pico's website. I haven't ruled out the Mesa stuff yet though. I plan on...
Thanks for your reply Chester. Nothing is set in stone at this stage since I am just in the planning stages. I will most likely do servos on the axis as for the drives and interface I have not...
Ok, I am advancing with my retrofit of the lathe portion of a Smithy 1220Xl. The mill portion will be scrapped entirely as it is pretty worthless (and I have a cnc mill already). I really want to use...
It is an old Haas 4th axis that looks like a converted Rotary table, bought off ebay. Everything feels pretty solid, just want to get the control dialed in
I finally got around to finishing wiring up my rotary table and rough set-up of the parameters but I will need to dial in the table for accuracy and It occurred to me, that I don't have a good...
That is a shame about NC, I truly enjoyed reading his posts.
For me, I think that it is fair to say that what I know about bearings pales compare to what I don't know about bearings. When I...
FWIW, I looked at NSK's brochure for the ballscrew I have as well as their rolled ballscrew and they specify the same fixed end support for both. Fortunately I found one on ebay (NIB) relatively...
That is what I meant to say, preloading the bearings. I have been doing more research and it seems that the fixed end is the important side, so I will probably just suck it up. I don't really need C3...
I've read through all the reads I could find and couldn't find a definitive answer. Is there a difference in the fixed end support? For instance there are a ton of C-7 quality fixed end supports on...
VM.
I am looking at purchasing a lathe cam package and sort of stumbled across the Bobcad v-21 on their webpage. I have spent quite a bit of time reading through the Bobcad forum, so yes I am aware of...
I was looking at the EMC wiki and I really don't know what any of the numbers mean or how to interpret them. I will be needing to build a low cost computer to run my next build and would like to set...
That is what I more or less suspected (feared), that it would probably be best to go with a matched motor/drive system. Thanks Al
Is there something specific in the data sheets to look for or is it a case of looking at the drive and the motor and then calling the drive manufacturer to see if it will work?
Thanks for the replies. I must admit that I am very weak in this subject area (probably among many). Unfortunately Google really has let me down in terms of trying to find the different commutation...
What specifically do I need to look at? The more I read on AC and BLDC servo's and drives it seems that matching the drive and servo is a very tricky process. Is this the case? Or can someone give me...
Nothing?
Well here is where I stand at the moment. I can either pass on the indexing idea at the moment and jump on a low price 3phase induction motor and go that route for speed control, or let...
Chuck indexing
I've been digging through the old threads to see if this is a viable (cost effective) option to add to my Lathe conversion. I am sure I want to upgrade the underpowered motor I currently have. I...
Can anyone tell me what the differences are between the G251x and the G201X? I am going to retrofit the lathe portion of a smithy machine (scraping the mill) and was considering just using the 251x...
I have a Midas 1220XL that I have had for about 10 years now that needs the lathe seals replaced. I am thinking about doing a low cost CNC conversion for the lathe portion of the machine and...
