that path pilot is something that can be used

I thought PathPilot is a specific front-end of Linux CNC specifically for Tormach users?

[daniellyall]

you can use it on other machine you only get support if you use it on a tormach machine you can buy it. the other one on a pokeys is this https://www.youtube.com/watch?v=cm2LI_BT3Dk

its still sometime before it going

I think one concern is the pin outs are not compatible with Mach3 so it will require either rewiring or making a custom parallel cable if you're interfacing with a Mach3 drive box you already have. I did just that to interface with a G540.

Louieatienza, in that setup do you use the Eding board for all the inputs and outputs and just use the drivers from the g540?

You match up all you can wiith the cable, then pull out what you can't so you can wire them separately. For example direction and step are reversed on the Eding board, the watch dog is on a different pin, and there are a couple +5V lines available.

You can have a cable made online, make one yourself, or use ribbon cable to move each pin to the correct one on the G540. Just makes it look cleaner to use the i/o lugs on the G540.

Some specific comments about what is often different on the various systems.
Some is wrong on some hw, some is just not defined and 2 (or more) ways might be right.
Some is unusual, but could be right.

Parameters in motor acc/speed settings. Do they work correctly ?
(Many dont).

Probing: Write data on hit, or on re-it ? Write data or not if not hit (False data in probing) ?

Homing: Who does it, the motion controller hw or the controller sw ?
Does it trigger on hit, or-release.
Can it do a fast-hit, then slow-re-hit, then release and trigger on release ?
How is homing handled on slaved axies ?
What about when they dont hit at the same time ?
How many axes can you slave ? Is there a limit ?

Is lathe B axis (tailstock) supported ?

Can you home 6 axes + spindle, all at the same time ?
Can they do the more accurate re-hit and trigger on release ?

Css on lathe. Does it work ?
Rear toolpost on lathe. Does it work ?
Radius and tooltip compensation on 2 toolposts or more (lathe). Does radius OR wear compensation exist ?
Does it work ?
Radius and tooltip compensation for live tooling (y axis) on lathe ?
Does it work ?

Threading pullouts.
Is there a metric/imperial bug, and does the pullout angle work ?
How FAST can you pullout ? How accurate is the pullout point ?
Does this work correctly in both radius and diameter ?

Supports Encoder inputs to machine sw for high-accuracy dros ? How fast ? How Many ?
MPGs ? How Many ? Handled in hw ? What latency ?

All above is stuff I have seen work wrong, or different, on some controllers, in some situations.
Some stuff does not work, at all, on Mach3.
Some stuff will eventually work in Mach4.

All above can be critical (if you have the feature) for functioning.
Some users may not care about some features, so they wont mind.

None is well and clearly documented, in any controller I know of.
A huge variety of hw exists, and proper documentation is needed.

I wrote the list to explain, in part, why
1. its harder than it looks
2. what is actually needed

Many people might "think" they have a "good product", but its actually not necessarily so, if it does not implement, and does not document (working or not), standard features.

Does not mean it does not do the job, but many things DO NEED to work for the product to be called "good".

I feel a good feature set, minimum, is:
MPGs in hw. Must not, absolutely, work through usb, as they need millisecond response.
Probing. Likewise.
Homing, slaved axis support either working or documented- not- available.
Servo spindle(s).

Basic g-code: commands, moves, arcs, homing, probing
Threading (with encoders) and CSS on lathe.

Documentation:
Exact definition ie documentation on how homing, works, per axis.
(1-or-2 hits, trigger on hit or release, re-hit-and-release, and so on).
Docs on encoder homing.
Docs on slaving.
Docs on probing.

Wiring:
Docs, per axis, with enable and disable, individually each axis.
Wiring differential drives, and single-ended drives.
Wiring the disable-signal to drives on hitting limit switches.

Desired:
Encoder inputs, fast encoder inputs, many MPGs at once (dedicated jog wheels are great !)
2 toolchangers on lathe.
B-axis on lathe.
Y axis support.
Dual spindle support on lathe.

Hw:
Ideally, 1 mhz pulse speeds, and encoder support for 1 mhz or faster encoder inputs.
Ideally, glass scale secondary feedback.

Overall:
This is just a fast overview list of the kind of things that may trip you, or may make a controller not be usable.
Both probing and MPGs are really important, and accurate encoder threading and css on lathes are important.

Here's another thing I didn't really consider. Post processor support for different cam programs. Most cam programs seem to have a post process that works for mach 3. I actually didn't see see one for Eding in Vcarve, unless its called something else. I use HSMexpress and vcarve primarly.

[daniellyall]

I just ask Eding if they have one for V carve pro

hanermo your on to it

one thing a lot of nobs don't know is what they need before they buy a cam product after they get it and its wrong well do they scream most time`s they do, but who`s fault is it the person for not doing research or company's have bad doc`s on there product

[xjdubber]

I need 256 kHz, or more, 512 kHz is enough, at the moment, but soon it will be 2 Mhz.
For servos, like on all really good stuff.

At that high of a pulse rate are you using encoder feedback? Better be extrememly carefull with wiring at 5v ttl its very easy to get problems even a switching power supply could do it at that point.

[daniellyall]

here`s the reply from Eding

The standard "G Code arcs mm *.tap" supplied with V Carve will work fine.
Newer versions of vectric products may also have the USBCNC post processor.
Also the post processor of vectric products are easily adaptable to your own needs.
Regards,
Bert

they are both in V C 8

[louieatienza]

You can use the EMC post processor in VCarve. With OneCNC I use the FANUC post processor.

I am in the same situation, what motion control to choice for 3 axis mill + one rotatory and maybe I will go for eding because it is software and hardware from the same people and because I receive quick replay from support (I don*t know after buying if it is same quick).
Expensive it is expensive, 999 euro the best break board, and not too much information about how to... or tutorials.
Complicate choice, for me.
