problems Chinise Router NcStudio

[wizzardworks]

Desmond, My NC studio is version 4.53 and came with a 600mm by 900 mmwork area. It is advertised as an engraving machine also. You might contact SALE CNC Router Milling, CNC Laser, CNC plasma machine, China, Servo Motor Drive, UK, USA, Italy, Spain, Thailand to see if they have a manual for your machine in english. I think you are trying to access the menu section where you calibrate the amount of travel per step. It is in the manufactory meny accessable with a password. The default password is ncstudio
The first mouse click is on the window tab and then perameter on the displayed list. The third mouse click is the "manufactory" button on the left. Then you type in the password (ncstudio) and scroll down. If no mirrorX and mirrorY checkboxes there are two options. The first one is try to enter a negative value in one of the calibration boxes. Mine came with a default of
.00500 and I changed both X and Y to .00625 for nema 34 motors and aparently for nema 23 the values are .003125 My z worked out to .00475.
You might try entering for instance -.003125 for the X and leave the Ywith a positive value like .003125.
A second alternative would be do a yahoo search for stepper motor wireing. There is a standard color code and two wires would be swapped. The cables are crimped and soldered connections, however if you have a breakout board inside the case it is probably screw connections. cnczone has a lot of information from people building CNC tools and you could find something reading thru those posts. You would change one axis only not both.
If you are unable to turn the machine around you can likely mirror your part in the design software and run the G-code for that. I use meshcam3 to write G-code and it has a mirror option. I wrote 892Mb of g-code with meshcam3 last month alone. You could try it on a trial basis for 30 days.
If you are not useing G-code or M code there is a difference in the Z calibration. I have a select box which changes the Z axis direction for .ptl type code. This is basically used for 2.5D cutting of profiles or lettering a sign with a v-groove tool.

Hi
I have descoverd a new problem with the machine
it still engraves upside down and it is now squeezing the
jobs, Exp: a job of 600x700 it makes 400x700.
but it looks normal in the display panel.
I'm trully lost and I get no respons from the company we bought it from.
What can i do to solve these problems???

Detrigh, I drew my parts in Cad with the overall dimensions longer in the X direction than the Y direction. The solids were exported as a .stl file into "Meshcam3" to do the G-code. Then I ran the files on CNCsimulator ( free program) and discovered the X axis was the longer dimension and would limit me to a 25" wide part. I went back to Meshcam3 and rotated the solid 90 degrees and wrote a new G-code file whih worked fine. I could have rotated the solid in my Rhino4 CAD program as well but it was quicker just doing it in Meshcam3. If my parts hadn't exceeded 25" in either dimension it wouldn't have been a problem.
The size scaling comes from the perameter setting for steps (microsteps actually) per millimeter. This is seet in your CAM program running the router. If you are operating with NC studio there is a youtube video by Sale cnc that will demonstrate how to do it. Basically measure the travel for 30 jogs 10mm long and adjust the perameter until you get 30X10 of travel (300mm). I measured with a 12" dial caliper. the x and y perameters will normally be the same but the z travel may produce a different travel and require a different perameter number. This would be due to a different ball screw pitch on the z axis. My machine has NEMA 34 motors and 16mm ballscrews. I have heard the new machines are NEMA 23 which should not change the perameters but may have a different ballscrew lead as well. The perameters are the easiest way to correct your scale error, however you could scalt the solid in either the CAD program or G-code generator. The right way is go to machine/manufactory menu enter the password "ncstudio" and scroll down to the perameter for the steps per mm. The software is written to operate any 3 axis stepper motor system and ships with a ballpark leadscrew pitch which must be adjusted to what is installed on your machine.

hello,
ive just bought my first cnc router a chinnesse model. ive instaled everything but when i connect the router and open nc studio the machine moves on its own up to the end of the bed and keeps on trying to go further.i guess the problem is with the ncstudio version that i have.please help. is there anywhere i can get a good version of ncstudio? please email - kmagita@gmail.com (i got a version 5.5.6 on line but it crushes emmediately i open it. im running win xp )

novice82, It sounds like one of the axis is going to a home position. The fact that it doesn't stop at the mechanical limit switch sounds like the X, Y, and Z axis plugs are mixed up where you connected them to the machine control cabinet. The Y axis is the longer travel up and down the table along the guides under the edge of the table. The X axis is up on the gantry above the table and moves across the table. On my machine the Y axis moves 35 inches and the X axis moves 25 inches. If The X axis is pluged into the Y axis motor it wil not see the Y axis overtravel limit switches because it is looking for switches on the X axis which is not moving. You may have the Z axis pluged into the Y axis plug and the machine thinks it is raising the spindle and looking for spindle travel limit switches.
I would not load a program until the jog functions are all working the correct axis and directions of travel. You must also go to settings/ manufactory and type the password "ncstudio" to get to the perameters menu. If power on is moving the axis motors unplug them at the control box so they don't move and look down the list of perameters for something which would automatically home the machine. Then plug up one axis and make sure it moves with the correct direction input (X+ moves to the right and Y+ moves away from the frequency controller and start button end) When all three axis are on the right button if one or more moves the wrong direction you can reverse it by checking the box in the perameters list for that item. My machine was correctly and clearly labeled in english and it all jogged the right directions. You must also set the number of steps per millimeter of travel. The NCstudio runs on metric input G-code. I save my files as "Mach3MM.nc and except for a warning "G64 ignored" it runs great.
For your problem I would only plug in the Z axis and make sure Z+ raises the spindle and Z- lowers the spindle. Then add the X axis which moves across the table, and finally the Y which moves the long travel down the table.
If you have everything wired correctly and nothing looke odd in the perameters menu you might contace saleCNC.com for software. I have delt with them and recommend them. Also on this forum I got mine working from advice I got from
"butterknife". To troubleshoot your glitch it would be helpful to know just what you have "clicked" on after double clicking the NCstudio icon to launch the program.
