it looks to me that you need to set up a g55 for the opposite side. G54 was for the top side when you flip the part over you need to setup workpiece coordinate system for other side. hope this helps .

Hey look at the boltonhardware.com M4 mini mill comes with 4th preinstalled i think the work envelope would work for you as well its 6,999 plus shipping. They get them manufactured by syil and are...

Hey if your axis' are going the wrong way, go into the homing and limits and check the reverse axis column for each axis that is moving opposite direction than what you want. This will make them move...

you may have to go in to axis calibration and change the acceleration and velocities if you want it to go faster as for steps per unit it is different for different set ups. If yours is working great...

It depends on the gcode for the road runner. If the gcode is for inches and you are doing it in mm than yes it is going to be to small. You might have to do some editing or switch the steps per unit...

the way i did it was in the settings tab or ALT-6 and there is an axis calibration button right there above the reset button. Go through that and tell it to move a few units whether its inches or mm...

ok thanks txcncman, ya i just found out the compound is limited to the 45 degree angle but i did tell him he can rotate the actual post to get the desired angle. Thanks for the help.

Oh ok ya it looks pretty similar to that one. Im not sure exactly what its for, its on my friends machine and he is in a different state so i dont have a way to see what he is doing. but i do know he...

It is a compound, it sits right on top of the cross slide and it has a degree scale, and the tool post is on top of that.

It only goes to 45 though. I am trying to help a friend out so i am not at the machine i cant say exactly what is going on. either it just wont go that far or he is not able to tighten it down if he...

say i have a mahine and the tool post will only rotate to 45 degrees and i need it to go to 60 degrees for thread cutting, what could i do to fix this? Would i be able to get past it with tooling or...

You need to set that point as the g54 work offset as your 0,0 point and program from that point. If you mean that you want to use the point after shut off and use it the next day the best bet would...

if only i could do that. The 4th axis i have has mechanical stops in it, it barely allows for 1 full 360 degree rotation which i think in fact it only does about 357 degrees of rotation. I am just...

ok well the step calculator worked i am just not sure of how accurate it is because i am just doing it by eye with the degree wheel on the a axis. i have no way of verifying the accuracy. But i did...

ok i am not sure what the steps are supposed to be. it was at 2000 and that was to much. I saw in the mach manual how to do the step calibrate and just did it by eye and it came out to 400. i am on a...

ok so i dont think i am doing this right. I have on angular for a axis and the dro doesnt match up with the degrees on the 4th axis. it will spin about 10 degrees or so before it changes to 1.000 on...

ok thanks and that will automatically change when i change it from linear to angular?

ok kool thanks. do you know if i have to configure anything else for the angular such as changing the ratio or anything or is it standard that i can tell it one and it will rotate 1 degree?

How do you change the a axis from linear to angular motion?

oh ok. Thanks for the help.

so a center drill, (which is a normal drill you can buy at a hardware store?), can act like an endmill because the operation is basically a pocketing operation, I am using the write wizard on mach 3...

ok thanks. I ended up using the endmill i had. it was actually a 3mm so 0.12 inches and it came out decent. i Think it would come out sharper with a drill mill or a v-cutter though.

Would an 1/8th inch endmill work for doing some engraving or should i use a 60 degree drill mill or a v-cutter? thanks for the help.
I am machining aluminum.

visual mill is pretty good, i would also recommend sprutcam

Download the manual, i believe you need to go into to ports and pins and go to spindle setup. Make sure all the configuration are correct. I think in the manual it says what ones are supposed to go...

You need to pick the direction you want it to go towards.
There are 4 options 0 degrees, 90 degrees, 180 degrees or 270 degrees. Going from left to right you will want to pick 0 degrees. Hope this...
