Let’s break down the main parts of a CNC milling machine. Input devices in CNC machines include keyboards, touch screens, and other interfaces that allow you to enter instructions and data. These devices tell the machine how it needs to function to create the needed design. The CNC controller is the brain of CNC machinery.

Easel will change the Z-axis settings in GRBL. Unless you have an X-Carve, do not use easel as a sender, change to UGS, Candle or one of the numerous other GRBL sender . cnc. I homed the machine and ran it with no tool in it to see what reactions I get from my machine. The X and Y axis respond perfectly except for the Z axis. instead of moving .Then move your axis and zero them. After that load your code and run. You can always do a sanity check and move your Z axis down via the jogging buttons, when the tool tip gets to the top of the stock your Z DRO should be 0. If these things are correct, then the problem is something else, potentially your gcode or maybe lost steps. Hello all! I'm new to this forum and I'm looking for some help with a DIY CNC machine. I am mostly finished with my build, just wrapping up some loose ends and trying to learn a lot about CAM and machining. However, I am having an issue with my Z-axis. A little background on my machine: -Welded steel frame, 1500mm x 1000mm x 400mm linear guide .
If the balancing system for the Z plate is not exactly right the plate could creep either up or down. Many machines use air cylinders for the balance, if the regulator doesn't maintain the correct pressure things can slip. Industrial level machines use two cylinders, one on each side of the Z plate, to provide balanced forces. WCS G54 Z axis not correct after setting part Z axis.

But the DRO still reads that it is in the correct position (X0, Y0, Z0). And this happens even when the machine is running in the air and there is no material being cut. The distance that is lost in the positive Z direction seems to have a direct correlation with how much movement takes place in the Z axis. For example: I am brand new in all the world of the CNC machines. I bought a CNC 3020T-DJ and after hours spend on this forum I managed to connect it to the PC and configure it. Thanks a lot! My problem arrives when I want to move the CNC machine. Y axis and Z axis work fine, either via keyboard arrows or with the Mach3 jog, but I get no movement at all in .
Model of CNC Machine: Shark Pro Plus HD 2.0. Help with z axis. Post by jdunnett26 » Sun May 01, 2016 12:06 am. Hi, I have been having issues with the z axis not holding the programmed carving depth. I had set the carving depth at 0.1 inch I loaded the code into the shark control panel. Here’s how to perform a configuration reset.

Hello, I have made my own 3-axis engraving machine from scratch and have everything running well, but I need help with the Z-axis setup. I have only used the ports/pins and the homing/limits to set the direction and homing. I want to set z-axis home to the up position but the co-ordinates are working in reverse.
Hi all, I am running a fairly long job on the Maslow4, and I noticed that there is some inaccuracy, namely that lines that are supposed to be straight are curved near the start of the cut. I am cutting 3/4" plywood, and I realized that when generating the Gcode, I never marked the flag to keep the cutting bit down. As a result, when cutting out a contour, it runs the depth . Hello All, I am trying to mill a one inch piece of stock. I always seem to have problems with stock great than .75. I after fight with the machine to get zero on the stock, when i try to mill a .5 pocket it nearly goes thru the whole dang thing. I already wasted much wood, any help to trouble shoot would be great. Hi Earl --Glad you got it going again.My own Zenbot is a 12 x 16 and I found the Z-axis mount was neutrally balanced without a router in place. I also use a Bosch Colt which weighs about 3.6 lbs so I have used a 4.5 lb constant force spring to bring it back to neutral balance when the router is onboard. I am new to this machine and forum – When I execute a file even after using the probe or not the machine raises up and cuts air about 6 inches off the work. I also downloaded the OneFinity test file and it does the same thing .
Wondering if anyone has noticed the z axis not lifting to gcode value before moving to next cut start point during program execution. I’ve set home to 1mm above the stock, to avoid the bit dragging across as it moves. The screenshot shows that G0 Z4 has been executed, but obviously actual Z is right around 0, and usually is somewhere between +0.5 and -0.5mm and . I have been using the cnc usb controller and software for a few years now with no issues. Recently ALL my routines that have worked in the past all start the z axis about .25" above what has been defined as zero at the top of the work piece. The z-axis zero is set by mean of a touch plate, again, having been used successfully for a few years. I recently built a cnc and everything works fine except the z axis isn't moving how it should. When milling the z axis will get lower every time it retracts as if it is loosing steps. Also when I jog the machine it can't jog more than about 7mm in the z without stopping for a second then moving again almost as if it is binding.
The soft limits are set too conservatively by default preventing the axis from reaching its true lower limit. Note: This is most often seen on machines equipped with 12" Z Axis. Option 1: Update Mach4 to latest version. Option 2: Adjust the Z axis soft limit manually in Mach4 by navigating to: Configure -> Control -> Homing/Soft Limits.

What control software are you using.? Like Micheal says it very much sounds like the machines setup wrong. It's not uncommon for the Z axis to be set to a different number of steps to the X & Y axis in the control software.? Usually this is because the Z axis screw use's a smaller pitch so requires more steps to cover the same distance. . . . Been playing around with my Maslow 4 and for the most part enjoying the experience until now. There seems to be an issue with my z axis. But just one side. So I was moving the z axis up and down and noticed that only one side was actually moving. Swapped outputs on the controller board and problem stayed on the same side. Not controller board . Good day, I am using fusion 360 instead of the software my cnc machine comes with. I have created a .NC file and ran it in my cnc. I homed the machine and ran it with no tool in it to see what reactions I get from my machine. The X and Y axis respond perfectly except for the Z axis. instead of moving in +Z direction it will move in the -Z direction and visa versa (-Z . hi everyone, a few days ago i added planetary gear reductions to my Y-axis (the axis has 2 motors, one on each side). it's a 5/1 ratio and the machine runs smoother with it, and if a can get it to work correctly i'll do the X-axis as well. after i put the gear reduction in, i calibrated the axis again in the settings page in mach3. when i jog the y-axis with the steps per value .
