    Hi all,

    Flighty lurker, first time poster and absolute CNC newb here. A bad near purchase of a cnc unit out of PA two years ago left a sour taste for jumping into the field for a while but I will probably pull the trigger on the Jcut 6090 on Monday.

    I'm fairly well versed in a couple of 3d programs and feel I'll get the grasp of the program/artsy side of this fairly quickly. What does concern me are the previously mentioned communication glitches/problems with this unit and the NC Studio card. I won't have a clue to even know where to start to troubleshoot if I encounter some problem like that.

    Another unit I'm looking at is the SaleCNC aXJ6090 ( http://salecnc.com/catalog/product_i...f034af3a9703dd )for about the same price.

    I'm wondering if there are enough experienced users of set-ups like these whom I could beg assistance from when I (inevitably) run into some snags. Or, if some of the knowlegeable here could steer me to a comparable 'made here' set-up.

    Thanks,
    Rob

    Rob, I would look at anything Jinan Quick has to offer. Rocket's posts detail the small machine available from Quick. I just bought and received a 1218 router from quick and the quality is excellent. Also it's pretty easy to hook up another control board to the router if you want to use Mach 3 or UBSCNC (what I did) . JUst have them install the steppers, stepper drivers and power supplies. Whatever you do I would only send a deposit (20 to 30% and than ask for progress photos). From this board it seems like Jinan Quick has the most satisfied users and has proven to be reputable. They don't make a P.O.S. though so the cost is maybe a bit more. Thanks thats my 10 cents .

    Thanks. I found the JCut on ebay, so the 20 to 30% might be a bit tricky with them.

    It's my first cnc machine (i work with vinnyl plotters) and The dealer donīt explain me how to install it.The Artcam just don't work.The type3 don't show me the 6090a machine driver in the list.I donīt understand the ncstudio, when i'm looking for the control point, the machine head goes to its limits (right & top)
    and i canīt export files from the type 3.SO PLEASE, IF YOU CAN HELP ME:

    1-Which is the machine i must to select on the type3 "add machine" command.
    2.Which is the good file exchange format? (from type3 to ncstudio)
    3. Is the artcam more easy than type3 ? Must i to install another version?
    4. When i send the machine to its control set point it goes ouf of the table.
    (Must the zero point to be out of the table?

    Well i suposse you are busy, but it is very important for me, the time goes on

    Default Any further thoughts on JCUT-6090A Chinese CNC's

    Hi Tew and javieronandia,

    I'm also now looking at the JCUT-6090A (for $2390USD) and wondered if you both are happy with yours and think they are good value? I'd mainly use mine for wood but I'd also like to machine aluminium up to around 1/4" thick, do you think it would be powerfull and accurate enough? Have wither of you machine any aluminium with yours, and how did it go?

    cheers,
    Ian

    Hi Ian,

    I realize you didn't address this question to me, but I will throw in my 2 cents.

    I bought a JCut 6090A and like it very much. It is very accurate. I had oversized motors and screws added and had a 2.2kw spindle added so it is not the stock model. I should have tried the NCStudio software before I took it off, but I did not. I converted the machine to WinCNC because that is the controller that I am familiar with.

    I have not had ANY problems with the machine. Mechanically it is very sound. I dealt with Mandy.

    Good luck,

    Butterknife

    Hi Butterknife,

    Thanks for responding, I've gone and ordered a 6090B from JCut or j-Cut, i'm confused there seems so many from the same province? I stayed with the 1.5KW water cooled spindle, and it seems it has 85BYG450A steppers, and 2M542 drivers, along with a rotary axis. The B has the rack and pinion instead of the round rails and bearings. It's being assembled this week. I don't understand the huge disparity between the quality and construction of these machines from the forums, as they all look like variants of the exact same machine, like rebranding?

    I just hope there's a way I can still export my normal mach3 gcode from Aspire at work and load it into the NCStudio, like a dumb interpreter? Actually, I've just realised that the pics Shanny from there sent included the one of your alphabet snake!

    cheers,
    Ian

    The 1.5 KW is 2 horse power so that's still quite a bit of power. The 85byg450a is a good motor. I don't know the drivers, but it looks like it outputs enough amps for your motors.

    I think you'll like your rack and pinion. I think it will have less drag than the ballscrew. And your linear rails and bearings are probably going to be better than my round rails and bearings.

    I can't speak for all of their machines. I have mine and it is a great little machine. I helped another guy who bought a 6090A who lives 35 miles from me. He ordered his set up for Mach3. I was able to get it set up online through Crossloop.

    I think in China, all of the factories copy each others machines. I think they don't have copyrights.

    I think most of your Mach 3 code will probably work with NC Studio but I can't say for sure. I wish you'd have gotten it set up for Mach.

    I did away with the NC Studio stuff and put on WinCNC.

    As far as my picture goes, I gave a couple to Mandy. She was very helpful to me and provided me a very good machine at a very reasonable price. I figure that is the least I could do for her.

    Good luck with yours,

    Butterknife

    I'm hoping as you had a good experience with Mandy and the machine you bought, that they are the same company i'm dealing with now. I wish I had looked into NCStudio before I sorted out the machine as I really would have preferred a Mach3 setup, as that's what I'm used to. I see others say NCStudio is really good, but for my simple needs Mach3 is the bee's knees!

    I don't think it would be that hard though to change to Mach3, so long as I have all the motor and leadscrew parameters, but when it comes I'll see how NCStudio goes before I try anything else further.

    cheers,
    Ian

    Hey Ian,

    Here was my wiring for the NC Studio software.

    1. Unhooked, but I think it was for a tool touch off switch.
    2. Step signal for axis 1
    3. Step signal for axis 2
    4. Step signal for axis 3
    5. X3 on the Sunfar inverter. It was set up for 3 outputs to control speed.
    6. Z high limit switch
    7. Y low limit switch
    8. X low limit switch
    9. Direction signal for axis 3
    10. Direction signal for axis 2
    11. Direction signal for axis 1
    12. X1 on the Sunfar inverter. Another of the speed outputs.
    13. X2 on the Sunfar inverter. Combinations of the 3 make up to 9 speeds.
    14. 5v- for everything.
    15. 5v+ for inverter, and steppers.

    I can't promise yours will be the same, but this was mine.

    I found mine by toning out the wiring.

    I never ran my machine from NC Studio, I cut out the 15 pin plug from the box and added a 37 pin D-Sub connector for WinCNC. It is the controller I use at work and I am used to it.

    I got a rotary axis too Ian. It was set up so that you moved Y to where you wanted it, then at the back of the machine, you unplugged it and plugged in the rotary axis in its place.

    I added another drive for it and a seperate mic jack for it to plug into. That way I can use my X, Y, Z, and A at the same time.

    I will copy this over into my own thread later and add the wiring changes I did for the inverter and for WinCNC.

    Hope this helps,

    Butterknife
