Error 907 Z Axis Travel Exceeded After Homing
Posted: Tue Feb 15, 2022 5:37 pm
Hello,
My name is Mike and I purchased a CNC milling machine with an Acorn Pro control board back in May of 2019. When I brought the machine home and re-set everything up, it worked fine. I could home the machine, jog all of the axes and input MDI commands. The original owner, who is a PE and worked in the automation field, did a beautiful job retrofitting the machine with the Centroid Acorn controller. The machine originally had a German language software and he had difficulty selling the machine, so he retrofitted it. I had to wait for some new bellows type way covers before I actually made chips with the mill from the German manufacturer which took four months to receive.
In September of 2019, with the machine now mechanically ready to use, I started everything up and successfully homed the machine. I was able to jog the X and Y axes after homing, but when I tried to jog the Z axis in the (-) direction away from the home position, I received a 907 'Z axis travel exceeded' error. I can jog the Z axis in the Z + direction, but not in the Z - direction. I also tried to move the Z axis with a MDI command and was unsuccessful.
I tried searching the forum, but didn't see anything relevant. This still has the original Acorn Pro v4.12 software installed because it worked fine originally and I didn't want to update the software until I found out why this is happening.
I am not very up to date with computers and think I am in way over my head here. Have been a machinist and toolmaker for 40 years doing mostly manual machining. Have used CNC machines in the past like a Maho Toolroom Mill and wrote the short programs manually or used MDI. This was back in the late 1980's and 90's when the programs were typed line by line into the control, we didn't even have a pc in the shop. Bought this CNC milling machine to make master cams for a cam grinder and other parts for models. As it sits in my shop waiting for me to find a solution, I have just continued on with other projects. Hopefully, there is a simple solution to this problem and someone has run into it before.
I made a report file and will attach it.
Thanks in advance for any help you can provide.
Kind regards,
Mike
