So, I recently unalived my cnc computer. I do have a laptop as a backup. The laptop has my registered copy of mach3, and a demo copy. Only the demo works. I still have not finished setting up the...

Hello all. I have a licensed copy of mach 3 with the wizards ad on. Im trying to generate a rectangular pocket with a round bottom. So, I want a pocket .7" wide, by 6.7" long, and .3" deep with a...

Im a bit concerned about bagging up the steppers. On my router, the motors get pretty warm, mildly hot when being used. I am also considering using the hybrid closed loop steppers with encoders as...

Hello. Im in the process of building a g0704 cnc conversion. I plan to cut aluminum mostly with this. I would like to use a good amount of flood coolant so the parts can be ve very well finished. Im...

Hi all. Im looking for pictures and information regarding a way oiler system for a g0704 or bf20 mill. Im not looking to buy the 50 dollar info pack that is available. If anybody has pictures and...

As in the pictures below,I would like to be able to really make the most of a sheet of carbon fiber. I figure my waste material is about 20-25% right now if Im lucky. Would like to reduce that to...

Hi folks. I have been cutting simple 2d parts for a while now, and am now trying to make it easier to organize parts on a sheet of material. I just discovered g68 and g69 for rotating the code file...

Thanks for the input. I will see about running another OS on this computer. Unfortunately, its all I have. Actually my cnc computer is a win7 tower, but its in the garage, and I like to do cad work...

Very consistently when I try to use the parallel line function with small increments bobcad will crash. Here lately it has begun crashing if I try to make a parallel line at 1.5mm. I had been making...

Hi all. I had a good working program but win10 deleted it, and its too late to recover. I need a program to convert .txt back to a .dfx file. I specify .txt to .dfx, because I downloaded something to...

I paid for a license on this version when I bought my gecko controller,,,, so probably not going to spend more, unless I can upgrade for cheap?

Thanks. I tried that again, and it finally worked. Some of the buttons werent hilighting when I clicked them to "add". First time I tried all I could get to "add" were seperators,, none of the...

Hi all. I had my bobcad setup fairly well, but just a few minutes ago it freaked out. In the end, my tool bars got messed up. I had it set to display the basic trim extend button on the toolbar. So,...

Yes, thats a problem. I would prefer to raise the spindle slightly before plunging back in. Is there a way to assign a work offset in z to each of 9 passes, so that when the sub starts over, it can...

I was wondering about the step down as well. In simulation it shows the z movements in the correct places, but not a measurement of each z move. However, theg01 g91 z-.033 should take care of that?...

Final version so far. i added a couple of z moves to clear the endmill with a blast of air between cycles. I think this will work.

Thanks Jim!

Jim you fixed it! I copied and pasted your revised program into a fresh notpad, and ran it,, worked fine. So, i went ahead and edited the feed rate, and it worked fine again. So, I will finish the...

Another interesting little thing. I just wrote this shorter loop to test, and it ran perfectly first time. This program should make a 1x1 square starting at x0y0 and ending there, 5 passes.

heres the current configuration of my program. I put an M30 in right before the m99, also made sure to push "enter" button after typing m99, and added the % sighn. In this configuration, it will run...

Back to making 1 pass. I added the p0001, and the o0001. So it would not generate a tool path unless I remove the m99. After removing the m99, the simulator would run 1 pass.

Ok, so I took out the g01 z0. However, I dont think thats a problem because z0. would be set at the top of the material. So, g00 x0.y0.z.3 puts the spindle at .3 above, g01 z0. puts the spindle at...

Sorry if this is an old many times solved issue. I searched. Im trying to make 9 passes for a profile outline, with .033 z offset on each pass. I cant seem to get this to work. The f70 was just to...

Hi all. Im a user of bobcad v21 for a couple of years now. Its been good till recently. Sometimes, not every time, when I save a drawing, then go to re open it a few days later, the scale is all...

Thanks for this program. I can confirm it runs on win10 laptop. Yes, some funny arcs, but its a real time saver to recover lost drawings. Can always fill in the details, and delete extras myself.

It could be that the "torque" pot needs turned down inside the controller. I was playing with my g0704 controller trying to get more rpm, and if I turned the torque pot up too high, it pulsed. Check...

Hello. Im Brian from CO. Currently running a cnc router using a g540. I just bought a g0704 milldrill, and a set of ball screws. Looking forward to making it CNC.
