Hello,

I am using Vetric VCarve pro software. I purchased a 4 x 8 ATC CNC machine from China. It is From Quick CNCrouter. My machine is the P408 (It is also called K1325ATC). I have a stand alone computer with Mach3. I am trying to figure out the proper Post Processor. Unfortunately the support is in China and they speak Mandrin. I have asked what processor they would like me to use but so far I haven't had much luck. I have tried several ones from Vetric but none seem to work. The ones that I have tried start to work and then the machine stops and I get this error message.   Error!Buffer Write 31 times attempted. Terminating Usb..I am thinking I need the proper processor to start. What ideas do you have?

Cheers

Peter

Hi Peter,
  Sorry to hear of your troubles. I don't think the Post Processor is the issue. In Vcarve pro however if you select a metric post processor it should work. the error you are getting seems more like a Motion controller issue. Is there a Plugin that mach3 uses to talk to the motion controller? Do you have a licensed copy of Mach3? I'm not saying your copy is, but being from China it is likely that it is a cracked copy.

Thanks for answering Charlie. I reached out to Vetric and they recommended a Processsor that apears to be working. The machine came with Mach3 that appears to be licenced. it's not in my name but i am assuming it is in the name of someone where I purchased the machine from. Right now I am trying to set up the tools. The machine has an eight slot ATC with a tool lenght probe. I am struggling abit on how to set up the tools properly. I can command the machine to probe the tool in the T8 config menu. The same menu that was set up to tell the machine where the tools are in the ATC. If I go into the Tool Table menu I can name the tool and put in the diameter. I just need to figure out how to check the tool lenght and keep it saved in Mach3. Any ideas? I have tried to find videos on line but they only seem to show how to make the macros.
Cheers

Hi Charlie,
I thought I had things worked out with the proper processor. I did a simple circle and the program seemed to work properly. I tried to do a star that has more line codes. The tools needed to be changed and the machine did that fine. It then started working on the file and before it could start the machine stopped and the buffer error came up. -Error!Buffer Write 31 times attempted. Terminating Usb.. I thought i had it fixed but i have not. I think i figured out the tool length probe. I will go through the steps in another post to you.
Cheers

I want to make sure that I am using the tool length probe on my machine properly.
1.   I go into the tool table under config.
2.   I pick the tool number put in the tool name, Diameter of the tool, put a nominal number for length. Save the values.
3.   Under plugin control I go to XHC Ncpod Config.
4.   I go to the XT8 button, and the T8 Config screen opens. That is where I can command the machine to change tools and where the setting is for the ATC.
5.   I pick the tool that I want to probe. I hit the probe button and let the machine probe.
6.   Once it has probed, I go to the Offsets screen. I press the Set Tool Offset button and the Z off set value changes. I save it and go onto the next tool.


I am to assume that if I don’t change the tool, I don’t have to re probe until things change. I also assume that there is no automatic way for this to happen. I think it is set properly but how do I check what the height of the probe sensor is to the table height?

Hi Peter,

It may be a good idea to check out this thread and if the name of your Mach3 licence appears there you will need to purchace a new license to ensure that Mach3 performs as it should (Mach3 has an inbuilt license checking which detects certain Pirate Licenses then deliberately misbehaves).  https://www.machsupport.com/forum/index.php?topic=24331.0

You could also PM me the name on your license and I will check it against my list to verify that it is genuine.

Hi Peter,

Thanks for sending the PM.

Unfortunately you are using a well known Pirate License which will cause you problems with running Mach3 correctly. Before proceeding you should purchase and install a genuine Mach3 license which can be obtained from here;  https://www.machsupport.com/licensing/

Whilst Mach4 is an option I don't think XHC provide a fully working plugin for their controllers to use all of the Mach4 features so switching to Mach4 may involve changing out your Motion controller for something more suitable.

Hello,
I am going to see if I can get a proper license from where I purchased my machine from (I am not holding my breath!). Am I able to put in a proper license and keep all of the settings that I have inputted so far? Are you fairly hopeful that this should fix my buffer problem and my machine should work properly?
Cheers
Peter

Hi Peter,

You will only be able to purchase a genuine Mach3 licence from Artsoft/NFS or one of their authorised dealers (Good luck with trying to get a genuine license from a retailer that has already provided you with a Pirate copy).

Installing a genuine licence will enable you to keep all of your existing settings.

There are no gurantees because your buffer problem relates more to the XHC motion controller, all I can say is that you will never be able to sucessfully run Mach3 with the Pirate licence.

Hello,
I just purchased a proper license and installed it into Mach3. I went to run a fairly simple program and I came up with the same problem a buffer error. I was hoping getting a proper license would solve this problem but I guess its deeper than I Thought. Any ideas? I was hoping to send a screen shot but I can't paste it in this window. Not sure how to send a screen shot if you need it. This is the history in note book.
