Re: Where are we in Mach 4
开云体育Hi Brian: ? I posted on the Machsupport Forum about this. I am using an ESS, but before I even et to that point, things go haywire. ? -After install of Mach4, when I try to run it, it says that "the application cannot run because the configuration is incorrect". Based on a tip from someone on the Machsupport forum, i installed Gearotic, and then manually ran the VC++ redistributable install from Gearotic, and was then able to run Mach4GUI. But after running the GUI a few times, it started to not appear on teh screen, that is, there would be a process called Mach4GUI, but I would never see it on my monitor. ? -So in that state, I could run wxmach, and it does appear on my screen, but as soon as I try to setup the ESS plugin, Mach4 crashes. ?

Re: Mach4 Comp new mode
开云体育Hello Sage,I don't think that is ignorance at all! This is a little not standard and I had to find a way to make comp work 2 ways and not break the old files that where out there. So here is what I did : G40.1 is the Old Arc type G40.2 is the new linear type Yes you can swap the comp type on the fly! I am getting good at this sort of thing LOL.. .Here is an Example file that shows a swap mid program: G90 G0 X0.0 Y-1 Z0 G40.1 (Arc Cap) G01 G90 G41 P0.25 Y0.0F60 Z-.1( .5 for the tool DIA) X-1 G40.2 (Linear Cap) Y2 X0 G40.1 (Back to Arc) Y0 X1 X0 G40 Y-1 G0 Z.5 G90 M30 The issue with the Yasnac type of cap is that it will make a gouge on very small comp moves.. I wish I could show it here for you.. But you have the power to pick the way you like best now and I think that is going to be the best for everyone! Thanks Brian On 3/7/2015 7:39 AM, 'Dave Sage'

Re: Where are we in Mach 4
开云体育Hi Jerry,We are starting on the wizards for turn as soon as we get the new version out. We added pocketing of any shape with islands too the wizards but it is very untested at this point. This was the last "to do" we had before turn... The fun part of this is that we are going to use this same code to produce the Lathe cut path so you can turn any shape in the Turn wizards! This is going to make for a very powerful set of wizards in Turn. Mach motion tested turn and they where shocked how nice it is working and we are not calling it finished. There are many ways to do Probe.. what are you thinking? Find Center and edge? or are you thinking tool length probe? I have a guy I can pay to get the scripts or Gcode to do this so I just need some clear picture of what you think you need. Now on another note if you are running the industrial version we can now run the "Fanuc standard" Renishaw Macro's so for users that are into that level they can used what is considered to be the best in the world for Probing parts.

Re: Spindle
开云体育Hi Spencer
?
Is your spindle rpm correct for the size of cutter,
number of flutes, depth of cut, feed rate and you are using a sharp
cutter??
If you can answer yes to all of the above and the
motor overheats it is probably doing too much work.
?
I am not into
woodworking so don't know power required for your application.
You could try reducing the feed rate to give the
motor less work.
?
Perhaps you can partly enclose the motor casing/end
plate and use a fan to force cooling air over the motor body.

EMCO PC5 "clipped chip" G03 programming problems
I
purchased a "clipped chip" PC5 lathe and when running Mach3 I cannot
execute G03 radius's on my parts. I am using the old EMCO PC5 software
to program my drawings. The challenge is on G03 the "K" value causes the
Mach 3 to stop on that line of code. The code appears to use the
correct (-) value and the radius is counter clockwise. I tried putting
the G91.1 & G90.1 with no results both on the line at the G03
command & at the top of the program.
?Secondly the tailstock ram has gone out of adjustment and I have tried to get it adjusted properly for drilling or setting the live\dead centers but no go. It seems to have all of its parts. The tailstock handle just unscrews itself. I have never had to mess with this before, can anyone shed some light on this? |

Re: Spindle
Spencer Chase
开云体育Marcus,I have the Baumuller. After replacing the wiring to the brushes and soldering it to the brush holders instead of using the tiny connectors it seems to be working fine. It does overheat if i run it with heavy loads at high speed for a long time. Unfortunately this is what i need to do. I do appreciate the quietness. Would it make sense to add a cooling plate to the motor and make it water cooled? I am running it close to max speed and am cutting 1/2" maple with a 1/4" good quality carbide upspiral bit and am cutting at 40 inches per minute. The motor speed controller keeps the speed constant and all works well until the motor gets hot and starts to loose power. Then i need to stop and let it cool. I think it failed when i did not do this and it got slow enough to not cut and broke a cutter. would the ZME with fan work better and is it possible to get for a reasonable price? i don't think they are in business anymore.

Re: Spindle
开云体育Hi Spencer
I am not certain of the motor used on your Emco,
but the PM 180v DC 4000rpm is the same as on the F1 milling machine
intended for working with steel so lower max
spindle rpm of 2000, achieved by pulleys and belt but with reduction rather than
increase as on the F1 Woodworker.
Original makers were either KEMO (with ZME 200-278
or without ZME 200-285 external fan cooling) or BAUMULLER ZME
200-290
The ZME part numbers refer to original replacement
brushes.
?
Changing to a router type spindle may be the answer
but there will be LOTS more noise.

Re: Spindle
Spencer Chase
开云体育Emgee,It is not the woodworker. I just found some paperwork to identify the machine. It was an Emco VMC 100 but the tool changer has been removed. This time the motor failed it was a lead to one pair of brushes. The new brushes do not seem to be wearing too quickly although i should have measured them so i could compare.? there was a fair amount of carbon dust but i thought that was due to initial seating. the commutator does not look burned. Maybe it just burned the wire because it wsa overloaded for a long time and that was the weak point. Is there a suitable replacement that i can stick in the 68 mm hole? I will probably try a cheap router as big as i can fit unless this is totally pointless. The original motor is a huge PM DC thing running at 180 volts. It has a belt drive but it is not two to one, closer to one to one. Forget the brand but it is German or Austrian and seems very well built. Does it make sense to have it professionally rebuilt, or just replace all the wiring? This time i just fixed the bad wire to two brushes, probably should have done both. I can add thermal protection. I have some little temp sensors that are programmable and can be used to cut the enable line to the DC motor controller. On 3/7/2015 3:15 AM, m.wg@...

Re: Mach4 Comp new mode
开云体育Excuse my ignorance but how do you USE two comp modes. You say one mode will be best for one circumstance and the other mode for a different circumstance. What if both those conditions occur in the same job. ?? Fine I guess if you are writing your own code. You can switch in the middle of the program. But if you have a CAM program you're going to have to decide on one or the other and change the post configuration before you generate the code. Then your out of luck for one or the other mode - NO? ? I feel sorry for the poor people that own Fanuc machines with lousy compensation - oh no - I feel sorry for the other guys that own the Yaskawa machines with lousy compensation. Are either of them really hurting so bad?? J J ? Sage ? |

Re: Spindle
开云体育Hi Spencer
?
If the Emco machine you have is the F1 Woodworker
then the original motor is a PM DC 4000 rpm type,
driving through a
1:2 belt set-up giving 8000 rpm on the spindle.
Sounds like you had too soft grade of carbon brush
replacement to wear out in short time.

Re: Spindle
Spencer Chase
I had my machine running and fiddled with speeds and feeds. Made about 200 parts half way and the spindle died. It is the original motor on an Emco old thing that i had converted to mill wooden parts. Spindle motor died before but it just seemed to only need brushes. This time it burned the wires to the brushes. I "fixed" the wires and then broke a carbide bit because it does not seem to have full power and i had maxed the feed speeds right before it died. It did not seem to be overloaded or i would have lowered the feed speeds.
I now need to install something reliable. I think i can limp through the parts i need immediately because the second phase is lighter cutting and i have not increased the feeds in the gcode beyond the original slow settings. Hope i don't break any more bits. The problem is that the hole into which i need to fit a spindle motor is only 68 mm in diameter and can not be made bigger. I need to cut with a 1/4" upspiral router bit and really want some decent feed speeds. Cutting maple which is pretty tough. I would like a motor that shuts down or complains instead of burning up. Currently using the DC brush type servo motor that is original to the machine and using a DC variable speed controller. Any ideas on what might fit the hole i have in this machine? The automation tech stuff is either too wimpy or too big to fit the hole and i am not thrilled with their stuff so anyway. The original motor is connected with a belt which is the reason for the diameter limit, it is a hole for the original spindle bearings that i need to fit the spindle in. could stay belt driven but i am not at my machine shop now and for a while so i need to get something together that does not require a lot of machining. the machine was working so well just before it died :) -- Best regards, Spencer Chase 67550-Bell Springs Rd.
