Hi Tony, how are you today. Thanks again for all your help. I am happy to report that the third one is the charm🎉😊. Now I don’t have my laptop with me at home today but the third one just arrived and I tried it right away with no computer hooked up to the machine. The wheel felt much smoother than the first two and it worked as soon as I powered up the machine😁😁🎉🎉.

@@Tonys.Top.Tips.Workshop thanks again, I actually use one almost identical at work on a lathe as a machinist so I’m looking forward to using it in the gemnitsu😊

Hi Tony, thank you for your film. I have exact the same configuration as you have, i only use the Makita router. I have no problem with this controller. I have a problem with the grbl controller. When I push the ‘home button’ of this controller, the z stepper motor goes up and will not stop. Also the end stop of the z axis does not work when I use the home button . I have today Saintsmart asked for help. I am sure they will help me.

Hi thanks for the info. Sorry your having problems sounds like the micro switch for the z axis is not working. Have you changed it with one of the spares that came with the machine.

@dobbie7454 Месяц назад

Thanks Tony for your reply. The micro switch works when I turn the z axis by hand and also when I use the mpg controller. It is also strange that when I use the home button only the z-axis moves and is going up and up. It only stops when I use the stop button. So even if the micro switch does not work, the home button will not function.It looks to me like a bug in the software. But I am new in this cnc world. I can still use the machine for everything else works fine. For your information: I use the Vcarve pro software and I also bought the x-axis extension kit.

@@dobbie7454 hi as you say sounds like software issue has the problem been since you extended the machine or firmware update

Thanks so much for all your help.Just to confirm a couple things. The first one worked a couple times, but I had to rotate the wheel back and forth, the wheel seemed tight and seemed to break free and then it started working, but then one time it just stopped working. The green light lights up on both of the yet it doesn’t move the machine.The control board they sent was the exact replacement as the old which is not the wifi one. The wheel seems tight on this one as well.The machine is so small, it’s not really necessary but nice to have.

I also tried connecting the way you show in the video and nothing, the green light is always powered up so I know that there is some kind of power going there. I’ve started a return but haven’t sent it back yet, not sure if I should try a third??
