Glad it worked for you, that was one of the frustrating things of learning ver. 20. The later versions have more integration and don't require the special switches. I only keep ver. 20 for the lathe...

If ver. 19 is like 20 which I have there is an item on the tool bar for 3D, this has to be turned on for it to generate z axis moves.

When you see the hand wheel move does it turn or just move down? If it doesn't turn but only slips down there is backlash in the system. If you have the Sherline stepper mount there is a backlash nut...

When I run Mach 3 I can scale each axis independently. So I would just set Y axis to 20% and the X axis normal.

I also upgraded to the A2Z kirk lead screws and with the 4 tpi screws you get rapids around 40 ips with the Sherline steppers. If I get rich I plan to go with the Gecko and a little larger steppers....

I can't tell for sure but it sounds to me like you are using the 2800 rpm spindle. I use the 10 K spindle and run about 7 or 8K I think you should be able to get to 10 or 12 IPM.

I was doubtful when Tim G. recommended the 10 TPI over the 20 TPI for my monster mill. He was right, the 10 TPI matches the stepper curve much better and I get higher speeds and the same accuracy as...

John, according to the Sherline web page the blue lathe was imported from Ron Sher. The one I first bought from Joe was a model 1100 metric imported from Ron Sher and sold by Sherline America, it is...

The size of the dove tail looks pretty close to the measurement I get on my OXA size QC tool holders.

Not so. I have BobCad V24 installed on the I: drive. Go to preferences/settings/files and make sure they reference your H: drive.

ps I'll just add that the way you get into the missing...

Most use a Gorton pantograph at 10:1 or 100:1 ratio from large sample. This smooths out the final product. I am looking at a Gorton at a local surplus machinery house right now for that purpose.

check your xml file, make sure you have the one for Gecko 540 loaded. also check the pin out and in settings in config.

I would first chain drill most of the material away, then mill with a roughing cutter.

Sherline makes their 3 and 4 jaw chucks on an r-8 shank for use in milling machines.
At least it used to be on their web site. check sherline.com and browse around.

Ok, I'm using Mach3, no tool changer but I have to use the post for the tool changer and then set Mach3 to stop on tool change.
If I use the post for no tool changer I get the same results you are...

look at:
Bronzes from Maria Laach, Germany - Good Shepherd Cross (bronze)

They seem to sell them.

Jeff you have broached what I was going to bring up next, I have only used the HiTech QC on engraving projects that were more 'artsy', not precision and I do admit that I've not gotten around to...

You make me laugh. It does remind me of my friend Gordon who always grumbles at the fast food places when we order the same meal and I pay less. I just tell him to ask for the senior discount. He's 7...

I have the A2Z monster Mill with the Sherline head stock and 10K RPM spindle. As I recall the changer is limited to 10K. I run around 8K on most of my work. Depth of cut is usually 6 to 10 thousands...

I got one when the price was low, about $149 for the changer and 3 ER16 tool holders. shortly after that they went to $300.
I really like them and now will have to make my own tool holders.

Welcome, Woodworker, I drilled down through your profile and it seems you are in Cleveland, Ohio I presume.

What size jet mill and what would you like to do with it? We need a little more...

Photomankc has it right, you must define what you want to do with the machine.
I have two lathes and three mills and for their size and horse power they are just fine, but you don't hog metal with...

I suppose that you have seen these:

I run mach3 and BobCad 23 on my A2Z monster mill. At first I chose the post with out tool changer and watched the machine just blow though all the tool changes where I wanted it to stop. Looking at...

I think what they are referring to is lower the point into the hole, gently until it is touching all around. I have mine mounted in an end mill holder firmly but still able to slide if I push it down...

So far if I think there is any backlash in the X or Y axis, I tear down the saddle and clean, lube and adjust everything back to spec and I see much less than .001" on those axes. The Z axis I have...

Yes, my Y axis broke just at the large end of the coupling cone, where the 5-40 screw ends. I sent it back for the end to be remade. While Tim was doing that I checked all the parts and found that...

Jon, I think you will be happy with the g-540 route, even though the Sherline set up is adequate the larger steppers will take more advantage of the extra torque from the lower stepping speed.
The 4...

I'm not running EMC2, but everything else is the monster mill with Sherline steppers and driver box under Mach3. The only comment is that the Sherline stepper is a little wimpy for the Z axis. I have...
