SMC4-4-16A16B SMC5-5-N-N

what software I can use for smc controller

Commonly used CAM software can be used, as long as you pay attention, not all G codes are supported, POWERMILL ARTCAM UG, etc.


SMC4-4-16A16B make a small round in the corner

Q :SMC4-4-16A16B and I hace an issue with my first hole. Im using Fusion 360, when I make the instructions for the hole, it seems is an perfect square but the final line, the boundary make a small round in the corner instead a straight 90 degree line. 

A:You can try. enabled cvl setting 1,CVL  is set to tool or fillet radius


Does the control support english dimensions (inches) ?

does the control support english dimensions (inches) ? Also – does it support constant velocity contouring?

You can enter inch data,What unit is the equivalent calculated in,it doesn’t support constant velocity contouring


Was it replaced by the ijk mode

I worked with it more and found that the cause of the error is happening because the ijk mode was not activated.

It seems that the instruction manual needs to be updated because there is no G02/G03 tolerance either.  Was it replaced by the ijk mode?

1. Use IJK circle center method 
2.  The post-processing setting of the CAM software closes the option greater than 180 degrees


smc4 system file


Yesterday we did something stupid, and after the successful firmware update gave the “G0XYZF” system command without the correct “system.rar” file on the MicroSD card. Now we lost the Chinese language altogether, and all the Chinese language characters are just a black square. English seems still to work almost fine, although some symbols are also missing when using English. Could you please supply to us the correct “system.rar” file with the English and Chinese languages?

I would be very grateful for this file and I feel very ashamed now that we used a system command we don’t fully understand.

(I also wonder if it would be possible for me to compile a special system.rar file with Finnish language? This would be also a very interesting project for later times. Our professors would be very pleased if I could show the device operating in Finnish language instead of English.)


SMC5 G-code

Q:I remark it is impossible to manage sub program (G7x codes) and also some codes to change tool (Tx, M6, Hx, …)
Do you plan to take it into account in the future ?

A:G7x is not currently supported, and AutoGM function can be used for tool change

Q:The function “All Shaft Reset” does not work correctly.
Axes Z,A,B – do not reset

A:“All shart reset” only clears the workpiece coordinates, is it the current display of the machine coordinates, clr origin is the clearing of the machine coordinates, or this, “Machine-home– referenceCoor–Zero DCoor”, this value is modified, the default value is 0


M47 command


The issue that we have in our machine is that the welding electrode is subject to wear, We should reset the tool (electrode) tip coordinates very often, every 2 parts. We need to reset the X and Y coordinates.
Our plan is to install 3 sensors wired to Input 1, 2 and 3 of the controller and write a sequence of commands using  the M301 … and G28 commands to reset the coordinates to current values to compensate the electrode wear at every execution of the program.
To do this, we need to create a conditional loop.    The question we have is about M47 command.  Is there a way to jump the program to another place than at the start of the program?
For example, to set the Y coordinate, we should place the tip of the tool on front of the Y axis sensor, the move a small amount the Y axis (0,1mm is OK for us), check the sensor, if not active, move another 0,1 until active, etc.


Currently there is only M47 loop, the latest one cannot solve its problem.

This problem is directly used to return to the machine origin command, G28 performs the return to origin operation before each machining, or set the tool setting point


smc5 upgrade problem

After upgrade my smc-5-5-n-n button dones not work Z-Axis Zero?

If there is no problem with the machine, initialize the parameters after the upgrade


“All Shaft Reset”does not work

“All shaft reset” only clears the working coordinates, is it currently displaying the machine coordinates, and “clr origin” is the clearing machine coordinates.
or please check if you change Machine  – home– referenceCoor–Zero DCoor,the default is 0

  • After stopping the G02 instruction, the milling motor goes through the path twice
    I use two SMC5-5-N-N controllers. For both controllers, I find that after stopping the G02 instruction, the milling motor (with the M05 instruction) goes through the path twice. Delete row M05 to cut the circle once. This is true even if you have M04 or M101 instead of M05.What could be the problem and the solution?
