SmoothStepper USB / Re: Smoothstepper step problem

So now I am curious what other things more important to users that are needed to be worked on first that puts this low on the list?

The evolution of Mach to rev4 and all that is required to get it done while also maintaining functionality and usability along with step change improvements to Mach3. The order of effort can only be determined by those actualy doing the work  and in that light i am sure the demands on those folks are great.There are more important things that need to be addressed than what has been discussed in this thread for sure.

So i will bluntly say that surely a concern will not go un-noted but will be addressed when appropriate
and not necessarily in the order we as users would like it. Such is life!

As I replied before, those who are dealing directly with the hardware and software would be the definitive source.
Thus we have tried to provide insight relative to your basic question as we relate to it.

I don't know as i am still in love with roadkill 033. That's all that was left on the trail after the elders got their pickens and wouldn't share the fresh meat. What more can i say, Phil, now you got the scoop! Maybe 037 will have more meat to go around.

I just noticed an add in Digital Machinist, by Eckler Software, usb to pp dongle to convert a PP cnc controller to
 a USB cnc controller. Know nothing about it or even looked into it.

Gandalfito,
Welcome to the site. The site is a great resource for users of Mach3.  You may want to consider translating to English in what you post. I had to use a translator to understand.
LOL,

when we were investigating something on threading

This had to do measuring  how many pulses were sent to the stepper as compared to output pulses from the index
relative to triggering the axis move. The electronic device measured to so many parts per million of pulses and could
add, subtract, or totalize the pulses from three or four inputs.It was used because,even very high end ditgital scopes are not
as good as that device / it's a custom counter. So you could see the affect of something put in line and compare and see if a pulse was lost. Something proved with pulse counting, was how belt tension and allignment can create a non movement ( call it backlash in the timing belts) of the axis which you would think was due to the ball screw or bearings when in fact it was lack of belt engagement to the pulley and even had an effect over time period ( small but real ).  So where's that lost ( for lack of a better word ) pulse relative to display and  mechanical movement can be get very complex. I'll leave the details to those that know what they are doing and just accept at times that all is well. Again i find out how stupid i am when i get into the expertise or discipline of another.

Not trying to curtail your quest for answers, just sharing experience FWIW,

Now I have another detail, when I make a template and ordered him to make a 'Pocket', the program to build parts and makes stops within the first machining herramineta there any option to do so without stopping,

You need the pro version of LazyCam to do pockets.

Sorry, i am trying, .........you Spanish----me Polish

millmaster,
On the lathe the X axis is 12700 steps / unit and i get that silly .0001" difference with the PP or SS.
 It means nothing,  and there is .0003 or 4 backlash anyway and there is nothing that can be done to eliminate it.

All the other axes on the other machines are over 20000 and never had a DRO problem. I am currently not using the SS since i got a new pc, can swap very easily if i wish. Thus i  haven't even tried the latest SS plugin.

What i remember from what someone posted  some time back on the DRO rounding, if the dro display was changed to show 10 places + you would see how things are being rounded. If a number was rounded, that small difference would be added to the next move .....don't take this as an absolute statement and it was some time ago and may be out of context. So no i can't tell why that is happening as it's beyond my understanding of the details. Greg would need to be the definitve source on the rounding manner for his HW.

Are you loosing a step / pulse ( .0001").....A friend came over with a custom built piece of electronic equipement ( borrowed from his workplace lab ) when we were investigating something on threading, i don't have anything that will measure a single lost step electronicaly. I doubt most folks do.

For position / mechanical movement i do it opticaly as it is easier only because i have the equipment to do it and it is much better than any indicator .

why so many? Ahhh......
This is realy a nice clean site with very, very few problems. Consider 24 hour coverage ,365 days a year, a lot of reading, a diversity of knowledge base, along with dedication to anyone. Takes a lot of folks to provide that kind of service to users.

You should not feel restrained in any manner, certainly jump right in there and clarify, comment constructively,
or bring knowledge to any subject / posting you wish. In fact if all the members were to look at each post and then reply only in an additive manner, wow, that's powerfull. There are newcomers that post and you can pursue helping them until you heart is content.

By all means question for understanding.

If you feel you have been slighted by a moderator, then send them an a constructive e-mail and explain as they all have thick skins and don't bleed easily.
