Normally, I would say great. However, if there is one place that I want reliability in a part, it is one that drives my robot, in this case the Tormach. With all the counterfeit and substandard...

The part is actually an IRF540. I ordered from DigiKey. Their p/n is IRF540PBF-ND The IRF540Z is made by International Rectifier and appears to have slightly better characteristics, lower on...

If you exceed the limit switch position you should be hitting a hard stop at the end of travel. If your motor continues to run, you are most likely slipping somewhere, I would check the motor...

For those concerned about the reliability of the motor connection on the Leadshine driver, here is a direct wiring replacement for the plug in connector. Phoenix P/N 1935349; DigiKey no....

I have used the left shift = Alt on startup method to get to the Gnome panel but it is a hit or miss proposition; annoying to say the least.

Today, I discovered an alternate method. When Path...

I am running my 770 on an Asus 16:9 HD monitor. When PP starts, it reverts to a default 1024 x 768 resolution so circles become ellipses but otherwise it runs OK.

I don't use the cabinet in the stand. My stand came with a leak. I believe that it is a weld above the angle re-enforcing strip. I drilled a weep hole at the rear of the cabinet but it is still...

Mike,

I had seen your post and it was a great help in understanding what was happening.

The connector chosen by Leadshine is not the best for this situation. Requirements for the connector are...

My 770 Startup package included the 770, the controller, stand, flood coolant system, TTS tooling package, tool assistant, moving kit, 6" 4th axis kit w/ 3 jaw chuck & tailstock, shuttle jog, clamp...

A couple of weeks ago, I was running a part on my PCNC770 when there was a strange loud noise during a z axis move. The noise only lasted a second and the program continued. There was a second...

Good point about the Jacobs taper. My first mill had only that option for tool holding. I finally put some super glue on the taper. Recently, I tried removing the adapter and no amount of...

One reason would be using the 770 as a vertical CNC lathe. I have several tools which have hex shanks.

What the OP's intent what, I don't know. He just asked how would he mount a 1/2" hex in the...

I just stumbled on this thread so please excuse if this has been proposed previously but the 1/2" keyed chuck that came with your TTS operator set will accept a 1/2 hex shank.

From what I see in the online manual for the 770, (page 171) the readout should be 17.5-18.5 for the 770 and 34 -36 for the 1100.

A temporary short across J2-4 and J2-2 on the 770 control board will defeat the y axis limit switch and allow movement. It appears to be the same for the 1100.

When I looked at specs for a replacement R8 collet, Crawford had the lowest specified TIR. Hardinge may be better but I couldn't find a TIR spec for their collets.

I actually rechecked the...

MY 770 got a replacement spindle cartridge under warranty due to a bearing failure. I had experienced severe run out with the replacement. After some detective work and a session at Tormach, we...

The motherboard ethernet hardware in my Tormach controller failed some time ago so I added an ethernet card. When I upgraded to PathPilot, I had to give up the ethernet card. I purchased an Edimax...

Thanks for the gnome-panel lead. I have been looking for a better way to access the gnome header.

I had previously set up several keyboard shortcuts, one of which was to bring up the Gnome...

I bought my spanner wrenches at the Tormach open house two years ago. As I recall, they were under $20 for the pair. I also made a torque indicator which I used rather than adjusting by feel. I...

Brian, you can't put the gib in backwards. It won't fit. Tormach had originally stated that on the 770, tightening left hand adjustment screw and loosening the right hand screw tightened the gib. ...

What you are missing is that the table is not necessarily flat or that the table may be lifting when extended to the far left due tothe center of gravity of the table now extended past the support...

I have a similar problem with my 770.

Lost motion really is not connected to your observed condition. It deals with bearing play, gib play, and lead screw twist with applied torque. I don't...

For cutting external geometry, I would expect lost motion to give a smaller than nominal dimension. It would appear to me that your running larger than nominal but the same in both x and y could be...

Tormach advises against repairing the 770 spindle assembly, stating the spindle cartridge must be replaced as a unit, due to balance of the spindle for 10K operation. (sect. 9.7, bullet 6 in the old...

I had a similar noise problem with my 770 as the spindle was coasting down. It was a spindle bearing. Tormach replaced the spindle cassette under warranty. That was four years ago and the problem...

If this were my new machine, I would press Tormach for an extended warranty on the table ways. Say five years? Any damage done by not having proper lube for the ways may not show up for some time. ...

As I recall, at the last Tormach open house, the Fusion reps. stated that the free version was the same as the version purchased by monthly or annual subscription. They also stated that Autodesk had...

I got the above offer as well, even though I have the free subscription.

If you are a student, an educator, a hobbyist, or a startup business with less than $100K/yr in revenue, Fusion 360 is...

+1 on solder.

I cut my teeth in electronics making soldered point to point connections. When I was experiencing connection failures of outside wiring due to corrosion, it became my practice to...
