Nope not me, but I I'd be interested in what it was.

I prefer my wood ground into sawdust and glued back together.? Well, not really but at least it's consistent for cutting.

Lasercut Avro 904K (circa 1913) in 3mm MDF.? Maybe 80mm wingspan?

Odd motion

 

¿ªÔÆÌåÓý

I had a friend ask this when he went back to his CNC machine after years of not using it.? His PC is rather flakey probably due to power supply capacitors. ??But anyway it seems he has his axis mixed up for what Fusion360 generates for G Code.

?

What he told me was that if he presses the Right Arrow Key the X axis motor moves the table but the DRO on the screen increments on Y distance.

?

What has he done to cause that sort of screw-up?

Thanks

Re: boots and lube

 

I have been using Febis K68 way lube on my ball screws and ways and have found it to stick well and not drip. There are other equivalent way lubes out there but I had to buy a 5 gallon pail up here in Canada and have a multi lifetime supply now.


Re: boots and lube

 

The only thing I can offer is that where I worked before I retired we used linear recirculating ball slides. They specifically said grease but do not use PTFE impregnated grease. This turned out to be harder that we first thought because when we looked into it a lot of greases had PTFE in them. My machines do not get a lot of use as they are hobby machines but I just use an aerosol glide-way lubricant on the ball screws once in a while.

Martin


boots and lube

 

my x axis screws do not seem to last very long. i just ordered boots for both side of the nut and who knows they might actually fit and ???

has anyone used boots to protect their ballscrews?

also what lube is correct to apply to the grease fitting for the cheap Chinese ball screws?

should i just buy the real thing a US made of German or Japanese? do they have better seals?

are there add on brush type or ? wipers.

Re: mach4 bug and other question

 

No big deal if i need to override the limit but i have? not figured out how without rebooting mach4. i can put a switch on the limit switch but then i will forget to turn it back on.

on the z axis i am pretty sure that trying to move to the limit mach4 automatically backs off even if you keep jogging to the switch repeatedly. the one exception is the x limit on the right side. if i jog to the left limit i can back off after reactivating.

it seems that mach4 does know the direction of travel when it hits the limit but only in the left moving direction on the x axis.

i tried to program a motion machine to work with just on limit switch for both directions and as simple the algorithm should have been, i never got it to work right,? so don't ask me to fix it :)

Subject: [MachCNC] mach4 bug and other question

First there is an annoying bug in mach4 that i can work around but often forget and i did break a bit because of this. I am using cheap bits but as of a few days from now I will be using very expensive bits and do not want to break them.

When you boot mach4 the step increment is shown in the jogging pane as what was previously selected. However the increment really is 1 in spite of what is shown. So when i get real close with the xbox controller and then want to make a .01" adjustment, it moves 1 inch instead which can cause it to crash. All i have to do is to remember to set the increment again but i keep forgetting.

I have shared home and limit switches for three of the four axis.
Everything works normally with the exception of one switch in one direction. If i hit a limit one of two possible things happens. On the z axis if i run into a limit it backs off or at least stops trying to pass the switch. i can then back off in the opposite direction. on other axis it triggers an estop and i need to enable again before i can back off.

However on the X axis if i hit the limit in the on the left it behaves as expected. if i hit the switch on the right it triggers an estop and there is nothing i can do to move that axis without rebooting mach4.
resetting the enable does not allow jogging off the switch. This is the case for just the x axis on the right. I had not noticed because i never hit the switches, i was just testing.

Subject: [MachCNC] CNC lathe questions

?

So I built up a Little Machine Shops minilathe with Mach4 and PoKeys57 ala the Techshops design put together by Joe Katona and Ron Ginger.

Works pretty good for small stuff. Minlathe needs physical tweaking and greater rigidity. I have an Enco 13X40 geared head lathe as well where I am doing more single point threading all the time and needing to do some larger diameter tapered threads. The minilathe just does not have the low end torque. So I keep looking at the mini Vs. the 13x40 and thinking about ball screws retrofitted to the the 13x40.

My concerns and thoughts;
If I retrofit with ball screws, I am under the impression that I would not be able to use the lathe in the old fashioned mode. The ball screws would allow the cross slide or carriage to move too freely or run away under pressure. Make sense?

If I replace the carriage lead screw, which one? The one for turning or threading. I could just disengage the quick change gear box. But the feed rate chart would have to be recalculated.

Other thoughts or concerns? Another lathe is out of the question.

Thought about getting a small X Y table and mount to the cross slide.

Thanks,

Dale Grice

Re: mach4 bug and other question

 

what about that x axis issue? i can not find any setting to try and the strange thing is that it is just this one direction on the one axis.

what MPG do you use? i am having fun with the xbox thing but could certainly use something better.

BTW, i have been cranking out parts and have had maybe one or two strange glitches that were probably windows related but no broken cutters or strange behavior.

Subject: [MachCNC] CNC lathe questions

?

So I built up a Little Machine Shops minilathe with Mach4 and PoKeys57 ala the Techshops design put together by Joe Katona and Ron Ginger.

Works pretty good for small stuff. Minlathe needs physical tweaking and greater rigidity. I have an Enco 13X40 geared head lathe as well where I am doing more single point threading all the time and needing to do some larger diameter tapered threads. The minilathe just does not have the low end torque. So I keep looking at the mini Vs. the 13x40 and thinking about ball screws retrofitted to the the 13x40.

My concerns and thoughts;
If I retrofit with ball screws, I am under the impression that I would not be able to use the lathe in the old fashioned mode. The ball screws would allow the cross slide or carriage to move too freely or run away under pressure. Make sense?

If I replace the carriage lead screw, which one? The one for turning or threading. I could just disengage the quick change gear box. But the feed rate chart would have to be recalculated.

Other thoughts or concerns? Another lathe is out of the question.

Thought about getting a small X Y table and mount to the cross slide.

Thanks,

Dale Grice

I was able to recover my original license. Thanks for the conversation on the topic.

are you the guy with the multiple axes artwork? i saved it as soon as it was posted and is one of my favorite images.

Subject: [MachCNC] is this possible

I am getting really tired of making the same parts i have been making
for 7 years. the only fun is making improvements. So I decided to
work on my gcode and clean it up and optimize tool motion. gets a
little scary when i get close to a fixture but i managed with no crashes.

I was previously (last many years) using various feed speeds and then
using feed override to get the speeds i really wanted. it has taken
years to fine tune the speeds to deal with varying grain etc etc.

BTW, running mach4 with ESS

So i changed every F command to double what it was and ran the
program.
I think i notice a significant improvement in finish. Specifically i
was getting long wood fiber threads on the top surfaces (upcutter but
ordered a bunch of other bits to try including expensive ones by Vortex.

This makes no sense to me but i have only cut 10 parts. Usually 5 are
OK and then one has some strange grain pattern in it and it comes out
stringy but after doubling the speeds (still that same speed in the
end because i use FRO of 100%) i have not had a stringy part and the finish
elsewhere looks better?
Am i hallucinating?

Re: is this possible

 

yes please do so, i am tired of this wood crap. can't they get control over these things? there should be a law.

seriously wood is an absolute bitch to "machine" if you are making a wood plaque it is not a big deal to do a little sanding but if you are making thousands of small parts that take a minute each to machine it seems like a waste when you have to spend as much time sanding off the threads.

i am getting close, hopefully the new bits will be the final solution, not that "final solution".

Re: is this possible

 

I'd say you've manage to find a decent feed & speed for that particular type of wood, so all good I guess.

Terrible stuff wood, just so inconsistent. Should be banned, I think I'll write to my local member and demand they sort it out.
