Hi folks
I m today little look software for LitePlacer and thinking , what is difference between OpenPnP and LitePlacer ?
I m today little look software for LitePlacer and thinking , what is difference between OpenPnP and LitePlacer ?
Sure that is on some part OpenPnP better and on some part is better Lite Placer , but if some one know that difference can write here .
When I m look video where locate hole on strep feeder I see that LitePlacer work perfect on that part , but with my experience with OpenPnP that is not some great function .
This can be very interested topic for develop OpenPnP .

There are a few major differences and lots of minor ones. mrandt has recently posted on the LitePlacer forum about this specific topic:
In my eyes, the major differences are:
* OpenPnP runs on Windows, Linux and Mac and LitePlacer is Windows only.
* LitePlacer is specifically designed for the LitePlacer hardware and has features specific to it, while OpenPnP is designed to run any type of machine and has some limitations due to that flexibility.
As mrandt posted, I see LitePlacer as a great all in one solution. If you want to buy a machine and have it work from day 1, LitePlacer is a great choice. If you want to build your own machine from scratch and have a project then OpenPnP is probably more suitable.
For reference, Juha (the creator of LitePlacer) and I are working together to make OpenPnP run on LitePlacer machines. This is not meant to replace the LitePlacer software, but to provide another option to LitePlacer customers who may be looking to experiment with another software.

I agree with you Jason if we look for diy machine , but all so OpenPnP have very frequently drastic changes in code and that is very hard follow if you are not software developer .
For you is maybe little better but you work on complete code and for that need allot time , I think that you then not have allot time for mechanic .
Cri.s is help me last 2 years on software , that is very good man and I m very grateful for that , but I wont develop machine who can work real job , not one or 2 pcb , machine who can work every day 8 hour min.
For that need software who is stable , that work boot vision , that can update every time when come new version with out drastic change , and that not need bother Cri.s for that .
You are make great job Jason , I m very happy with yours software , but maybe is time that define some fixed staff on openpnp .
For that I m run this topic that we see difference between LitePlacer and OpenPnP and maybe define some staff that will be fixed on all version if it is possible .

I have to respectfully disagree that OpenPnP undergoes drastic change. When breaking changes are made they are posted to this mailing list along with information explaining how to mitigate the impact. The software also includes an in-depth test suite and changes that break the test suite are not allowed into the codebase.
It is important to note that Open Source is a two way street. I can't fix bugs I don't know about, and I can't support code that is hidden from me. You have been using a highly customized version of OpenPnP for several years and very few of those changes were submitted back to the project. It's unrealistic to think that custom code will continue to work without changes in software that is continuously undergoing development.
I think that you would find that if you keep up with releases, there are very few big changes that happen over the course of a machine's lifetime. Keeping up with incremental change is easy, but waiting 2+ years between upgrades is, of course, going to be much more difficult.

Yes I agree on some staff with you , that is true about beck up information , like I m say Cri.s is all must all problems repair and I m not add allot question to you , sorry for that .
I will try next time all problems add on this group .
But like I m say , this topic can be very good start position for compare some options and solution on other software that we can see what we can do to this software will be better .
You know that I m few time say that will be help full add park position , now we see that you are add it.

Or one time I m ask you why you not add speed for everyone component in work and you are add it .
Maybe will be nice compare some other options on other software or some part of code and see how advance this software .

I really like that LitePlacer very accurately locates holes in the centers of the tape, well and accurately detects fiducials points centers.
I really like the alignment of the components coordinates on the board across multiple fiducials points!
I use 6 points on the board and coordinate compensation works perfectly.
I also really like the backlash compensation function in LitePlacer.
It is very simple to realize.
The machine first moves in the coordinate X -0.5; Y -0.5, then moves to X; Y coordinate.
So the movement to the target coordinate is always from one side.
I just put a checkbox in LitePlaser and this greatly increased the accuracy of positioning.
But backlash in the mechanics did not allow me use OpenPNP.
I bought a linear encoders and set them on the machine, to eliminate free play and try to use my machine with OpenPNP.
(currently I am finishing the installation)

I see liteplacer as a machine with software, for those who just want to get going.
I see OpenPNP as software for machines. Eventually I think we'll have "made for OpenPNP" kits, but for now its great for the DIY crowd.

Personally I have never considered the liteplacer a machine capable of running for hours on end all day every day. I have no interest or patience to fiddle with wheels that ride on extrusion ever again.
On the other hand we have run our machine with OpenPNP for hours on end and produced a tremendous amount of product and have been left wanting for very little save it be a nice way to feed parts (still working on that) but for me OpenPNP and a nicely built diy (rails based) machine checks all the boxes.

I agree with you Anthony for LitePlacer , that construction is not possible that work every day hour and hour , that I m not wont say , but you must say that on LitePlacer have some staff in software that work better , on that I think for sample hole detection on strip feeder .
OpenPnP is in most think better , but stay space for make some staff that can work more better .
Like Mixail is say have some staff that is better solved in LitePlacer , for sample that we can see code that is send to driver for sample , I know that we can see in terminal if run debug mode , but that will be nice options all so in OpenPnP .
I m see on old OpenPnP that drag feeder speed is be limited in some min speed , for sample same speed is be if add 100 mm/min or 300 mm/min , and after some speed then can see difference , now have speed in % , but dont know it is possible make for sample 0.2% speed for drag tape ?
My machine for sample go max 30 000 mm /min and that is for sample 500 mm/min , but on real job max speed for drag feeder need be for sample 100 mm/min but when speed is below 250 mm/min then all, time look me like same speed , or I m mistake something ???
I wont say that have allot space for compare this software with similar and see what we can do better .

Mixail can yo maybe make som video where we can see how work that hole detection on strep feeder ?
All so will be nice see some other staff that you are say that work better on LitePlacer.

That type of backlash compensation is no problem to implement inside driver.

Sorry, now I can not shoot video.
I disassembled a machine to replace the motors.
I'll do it when the build machine back.

Thank you,
I thought about it when Jason added GCodeDriver.
But now I have no need, because I set on the machine linear encoders, and it fully eliminates the problem of backlash.

If you reassemble the machine, check that machine is sqare. On Openpnp
this is requirement,
on liteplacer this is compenstated in sw.
Exemple if you have 40 cm on X and 30cm on Y from zero origin,
then the distance from from the two points must be 50cm.
sqrt(x*x+y*y)
It's simple to do and to check if you are aware of this on assembly
and don't require special instruments to measure.

Hi Mr. S.Mitic
I will write on English because is not nice write on Serbian or Croatian if all other people write on English , but need say that my English is disaster , but I use it because all people on this forum write on English .

Mr. Mitic , I think that for you is better that not thin , maybe is better that try understand that this forum is for opensource software , on this forum people discuss what is ok on OpenPnP software , what not work ok , what will be nice change add and other staff .
When you will be ready use up more then 600 hour to modification software and when you will be ready use yours time for develop this project for all people on this forum and all so for me like Cri.s , who is be connected to my comp. and we are meet new year together on line , he in Italy and I in croatia and work on OpenPnP , when you will be ready like Jason spend few thousand hour on develop this software , when you will ready like other people make some machine , run that machine , constructively use this forum , then you can write me that I m assailant and boring , If you are not do all that I m write please then yours opinions keep to yourself .
I m work on develop 3 PnP machine now , first I am make before 2 year , second before 6 months and now work on third machine .
That machine will be have topic on this forum , if you wont comment you can if you not wont you not need , I m sure that have people who wont look that project , who will be ready help and all so constructively discussion on that topic .
