It is for local pick up only in or near the Mountain...

Hello,

I have my version drawn up using a MS Excel formula calculations and converted to a CAD model. I plan to cut these gears using the waterjet method. My question is, what is the tolerance...

I found out that reusing gcode requires knowledge of gcode programming. While it is possible to do this, I would rather rely on the Powermill GUI to make the changes. This would be more reliable...

I did not see a Mach3 post processor on the Delcam forums site. If someone sees it, can they please provide a link or post it on this site?

Here is an updated PowerMill Post processor. It was modified using Delcam's PM Post Processor 4.7.00. I performed simple tests using PowerMill 2010 and Mach3.

This version is for Mach3...

I found this searching the internet.

I already have G90 (absolute), but was not aware of G90.1 (absolute for IJ). Do these two have to be on different lines? Someone says G91 and G91.1 do need to be on different lines.

How about...

Is there a way to make Mach3 config settings directly from gcode? Sometimes I forget to set the Config > General > IJ Mode to "absolute". I would like to get this done automatically when the gcode...

Below is a picture of the Hypocycloidal gears I made via a spreadhseet and Solidworks. I found a document on this thread (I think) that states that the 2 matching gears should have the same...

Zoidberg, in post #72 of this thread and your 3 photos of the cycloidal gears, what are is the diameter of Y (pin rollers of lobe), eccentrity that was used, and diameter of X (of the outter gear)?. ...

bemfarmer,

This is regarding your spreadsheet for the hypo and epi cycloidal gears. If using the same R, r, N, and E variables, are the resulting calculations for the hypo and epi cycloidal gears...

For the Harmonic Drives, I was told that they have limited torque for a 5th axis. A better solution is a Cycloidial Drive which has zero backlash, can do 100:1 ratios, has lots of torque, and can...

Hello,

Several months ago, I had to remove my spindle motor on my IH mill. I was told to take a picture of the wiring box where the motor wires connect to a plastic box so that I would know how...

Has anyone tried using the Camnetics product called GearTeq for creating accurate CAD models of the Cycloidal Speed Reducers? I plan to make a 200:1 version for a rotary table which will go into a...

In post #260, you machined your own bronze bearings. How did you get that groove on the inside of the bearings? What maching process was that?

Looking forward to the results. This site has something equivalent:

I would think that laser cutting would not be accurate enough and...

That boring head has an accuracy of 0.001" or 0.02" per dial revolution. Is there any way to make it more accurate like 0.0001"?

Buying a 0.0001" accurate boring head set would cost about $1500...

What is the cost to build a DIY laser engraver assumming I already have an XYZ axies table? I plan to use it to cut balsa sheets to make RC airplanes. Here is an example:

I have to move my IH mill to a truck and want to first remove the 3HP/3Phase motor from the gear head housing so that an engine hoist can lift it high off the ground. I know there are bolts that...

I just reserved a 26' uhaul with 33" deck height and a ramp (no lift gate). The mill is in my garage so there will be a sloop. I will try removing the spindle motor and lowering the head to the...

Hello,

I am trying to move my IH mill (RF 45 type) into a truck rental that does not have a lift gate. Since trucks with lift gates are only for local moves, there isn't any available (do not...

I have another question. I need to use bearings for the 5th axis trunion table. These will be mounted to the aluminum plates that will stand up vertically to hold the horizontal table. I looked at...

I am looking for WorkNC G3 tutorials or manuals. A friend already showed me the docs that came with the software. But, I am looking for some other tutorials or manuals. Does anyone know where I...

I did not specify a preload code. For example, in the code XB3-A-100-100-C, the VB3-A is the harmonic gear type. The first 100 is the size in mm. The second 100 is the ratio (1:100). The C is...

I requested a price quote from www.hanzh.com for some Harmonic Drive Sets and Gears. This is what they sent me:

XB1-100-100-C : USD 600 (component set)
XB1-100-100-G : USD 730 (gear set)...

I read on another thread that Bob Warfield recommended using Harmonic Drives/Gears which offers zero backlash. I am indeed looking at this possibility and finding out the cost to get one of these. ...

rab, I plan on milling some M4/M16 rifle lower/upper parts and anything that my hobby interests can think of. There is some difficulty on doing it via 3-axis in that you have to re-adjust the stock...

I am planning to build a 5-axis CNC machine. I already have a 3-axis CNC mill and just need to build the 4 & 5th axis. The main requirement I have is that it be backlash free which general means it...

I did some research and there is a Hard Anodizing DIY process at http://www.diyanodizing.com/diy_hard_anodizing_kit.html. This would give the aluminum excellent hardness and corrosion resistance. ...
