A mutex is just an integer that counts up when someone grabs it and counts down when they release it. You can only grab the mutex when it is set to zero so you end up blocking if someone else has the mutex. If they were smart it would just have been called waitYourTurn() and imDone()
]]>At line 842 I call writeSerialPrintf() to send the command out, Then at line 844 I wait for a line to come back with the sub string "stat":"start" in it and then at line 845 I wait for a long time (up to 120 seconds) for a second line that has the string "stat":"complete". If the timeout is not provided to the waitForJsonVal() function then it is set to the default. Right now the default is 1/2 a second.
That is if I send out the command and don't get something back right away I know the printer is in a funky state and don't need to keep waiting. At that point the only thing that seems to work is to power cycle the printer...
The second waitForJsonVal() call waits a long time because it physically takes time for the motors to move.
]]>At line 834 you see the function jogPrinter that takes a character for the axis of 'x' 'y' or 'z' and an int for the distance in mm (0,1,2,3...)
The function writeSerialPrintf() takes a printf style formatting string and fills in the details then sends it out the serial port. here is the call for doing a jog:
m_serial.writeSerialPrintf("XYZv3/action=jog:{\"axis\":\"%c\",\"dir\":\"%c\",\"len\":\"%d\"}",
axis, (dist_mm < 0) ? '-' : '+', abs(dist_mm));
Here are the special characters and what they mean:
\" is an escape, it embeds the " character in the string rather than ending the string, just pretend that character is not there
The first %c says replace %c with the value of the first argument, that is the letter x,y,z from the axis variable
The second %c is replaced by the second argument: (dist_mm < 0) ? '-' : '+'. The argument is a ternary operator, everything inside the ()'s are tested for true or false and if true we exicute the code after the ? else we execute the code after the :. In this case we return + if dist_mm is positive and - if dist_mm is negative
Finally the %d says the third argument is an integer (digit?) and takes the value of abs(dist_mm). The function abs() returns the absolute value of the passed in variable, that is if the number is negative we remove the negative sign.
So basically if you were to call jogPrinter('y', -35) we would send this out the serial port: XYZv3/action=jog:{"axis":"y","dir":"-","len":"35"}<newline>
]]>// Jog where LL is step size
// make sure you have homed first?
XYZv3/action=jog:{"axis":"x","dir":"-","len":"LL"}
XYZv3/action=jog:{"axis":"x","dir":"+","len":"LL"}
XYZv3/action=jog:{"axis":"y","dir":"-","len":"LL"}
XYZv3/action=jog:{"axis":"y","dir":"+","len":"LL"}
XYZv3/action=jog:{"axis":"z","dir":"-","len":"LL"}
XYZv3/action=jog:{"axis":"z","dir":"+","len":"LL"}
// returns
jog:{"stat":"start"}
jog:{"stat":"complete"}

You should be able to type these by hand into any serial terminal. So to query all status you would type:
XYZv3/query=a<enter>
]]>I have not yet tried it but i will ....
One thing that i was thinking is .... if i for example would like to just query the printer for the info of what serielnumber firmwarenumber and so on .... How would i do that...
lets say i have a minicom connected to it .... do i put the query in the console and send it to the prineter?
and how would that query look like ...?
i can see this
XYZv3/query={}
XYZv3/action={}
XYZv3/config={}
XYZv3/upload={filename},{size}{option}
XYZv3/firmware={filename},{size}
XYZv3/uploadDidFinish
could i just in the minicom console put...
query=a
would that give me the info about it?
]]>GitHub hides it a bit but if you click on the release button you can see all the exe's
https://github.com/reality-boy/miniMover/releases
i can not see any configure script or make .... do i compile them one by one ?
do you have some instruction or is it just to start trying?
or even better .... do you have them compiled some ware that you can email me ?

]]>I will get back if i get stuck ...
When it comes to the porting i will have some problem .... i can only program in cobol85

This is more complete than the 3dub variants out there, it should replicate all aspects of the XYZWare application, other than actually slicing a model of course, you need your own slicer.
]]>I have no experience using threedub with miniMaker in Linux, but is does not hurt to try.
]]>I have bought an 'da vinci mini maker' it is not the wifi version ... so it only have usb
I as well have no windows computer but have found that they have released an ubuntu pakage of the 'XYZmaker'
I found it here ( support.xyzprinting.com/us_en/Help/download/xyzmaker?productName=XYZmaker )
that pakage seems to be a bit old as it is from 2016 but it was the one i found so i went for that...
in the ubuntu system i can see it like this:
sudo lsusb
Bus 006 Device 049: ID 11f1:2513
and in syslog like this:
Mar 7 16:13:37 xx kernel: [32002.940117] usb 6-1: new full-speed USB device number 51 using uhci_hcd
Mar 7 16:13:37 xx kernel: [32003.115172] usb 6-1: New USB device found, idVendor=11f1, idProduct=2513

Mar 7 16:13:37 xx mtp-probe: bus: 6, device: 51 was not an MTP device
and then i open XYZmaker...
it first tells me there is a new version and then directs me to there homepage but that shows the verion that i have ...
in the software i add an object and try to print but i can not find any printer ...
Is there anywhere that i can get the linux driver or kernel module?
or is there any fast and easy way to put any other open source firmware on it so that it works??
Best regards
