Ok. I got the bearings changed without too much trouble. There was plenty of room to pull the spindle out with the head cranked to the top. My bearings were a bit smaller than yours presumably...

I guess it should be somewhat apparent by measuring how much space is below the head with it all the way up vs the length of what's inside.
Not a problem.
I was also going to make a direct way of...

Thanks Art:

I like your method of breaking the taper loose.
I'll have a go at all of this over the next while. My machine is complicated by my conversion to CNC and the pulley's etc on the Z...

Hi Art:

Thanks for the quick response. I think we're still talking about the same machines here so I'll ask another couple of questions. The big nut on mine is a standard right hand thread. I've...

Art:

I'm reading your post on changing the spindle bearings with great interest as I'm about to do the same thing.
I haven't started yet but I think what you're saying makes some sense....

Sorry. Once I had posted this some suggestions showed up at the bottom of my post and one seems to be the answer I'm looking for.

I have one of your typical Taiwanese mill drills. They are pretty much all the same I think. I need to remove the spindle to replace the bearings. According to the (crappy at best) exploded diagram...

Yeah. Your probably right. I'm playing with the demo version and helping Art a bit with troubleshooting his PP driver. I believe you are as well ?. And you are right, it seems from what they've...

Hi Guys:

I thought I posted this earlier but it seems to have not shown up. Sorry if this is a repeat.

Mach 4 is coming soon !!

Greg: Can we count on you to write a new tool setter interface for Mach4. I can't live without it if/when I upgrade to Mach4.

I appreciate your work on the original.

Thanks Guys:
I'll pass this information along to my friend with the Flashcut controller and see what he can discover.
As mentioned I don't have Flashcut so I can't test your assumptions but they...

No more ideas guys?
There must be someone that knows Flashcut and what's wrong with this Gcode.

The machine would provide a smooth motion in X and A at the same time by - like you said - dividing the motion into a bunch of intermediate points in both axis'. The motion hardware only moves as...

Thanks Mike:

Are you equipped to give it a try? I'm surprised at the lack of response especially since this is supposed to be the CNC ZONE. I thought more people would be jumping at the...

Several Months ago I started a thread on Home Model Engine Machinist forum (HMEM) named "Grinding Cams - will this work"

Nope. Sorry.
They're all G0's

And the 4th line has a F1 and the that will stick for all the rest of the lines.

Any comment on the "A" being the rotary axis.

Even though it reports line 13 as the problem, apparently my friend deleted that whole line and it still won't run. Sometimes errors are just red herrings.

I'm wondering if it's the definition of...

Test message - please ignore.

Thanks

Thanks for moving my post from the general CNC questions forum. I didn't see this Flashcut forum.
There doesn't seem to be much activity here. Hopefully someone can answer my question. (above)

I know nothing about Flashcut. I'm posting this code snippet to help someone else.
All I can say is that it works fine in Mach3
Can anyone identify what Flashcut does not like about this code.
My...

I have a couple of suggestions:
First: Hand hold a temporary touch plate under the bit well above the table and let the bit touch that until you get it figured out. You'll save the damage to your...

FYI
I'd like to bring to your attention that I have developed a new way to make cams using a CNC mill and an off the shelf mini-grinder. It started as an experiment and turned out to be very...

Perhaps I can make you aware of another gotch-ya. You stated early on that you wanted the finished aluminum to be mirror-like. I have considerable experience with anodizing and I can tell you that...

Thanks Terry:
What did you use as a fuel pump? I was considering that apparoach as well. One question though - being that it does take at leat a bit of pressure to raise the fuel from below up to...

Wow !! You did a rellay nice job on that too. Especially for a first engine. You certainly have a nack.
Sounds really good. Are you using the TIM circuit for it as well. It's tough to tell on video...

Re the method of cam manufacture, I guess great minds think alike.
As you know the resulting action you get from a given cam depends a great deal on what you are using as a tappet (lifter). The...

Terry:

Did you develop a timing diagram for what you found? I'd be interested in seeing it. I also used a degree wheel for each cylinder but I didn't plot a complete diagram. I just measure the...
