Re: [Emc-users] It looks like I need help understanding 2.8.0
Is there a feature in Master that you need to run? When I'm not sure if I touched off correctly I do a chicken check by jogging the tool to a point I know what the DRO should read and see if the DRO is correct. AFAIK machine limits are in machine units and it won't matter if your in G7 or G8. As I said before as you type in the first number in the touch off box it immediately tells you if your in diameter or radius mode on the next line below the box where you enter the number. You can also look at the Active G-Codes: box and see if your in G7 or G8 and if your not where you expect change it in the MDI Command.

But now I am back to the G7/G8 diffs which are costing me money. This program, which looks great in the back plot, proceded to drive the carriage to half the diameter on the first loading, smashing the insert and unscrewing the QC toolpost generally raised hell. So I eventually killed LCNC, and when I had restarted it, and reloaded the code, now refuses to run because x maximum exceeds the machine limits. Those are set .1mm short of the homing switch, which itself is aboput .1mm from the maximum backup x can do on this toy, at about 67mm from the centerline. What I can see in the debug statements says it isn't so. x max is nominally 1/2 that limit as set in the .ini file. And the backplot image is exactly what I want it to do. The program: === G7 (diameter mode dammit) #_x_start_dia = 32.300 (x at left z DIAMETER) #_z_start = 105.50 #_x_taper = .32000 (in mm's, measured taper compensation needed) #_z_left= 0.000 #_x_end_dia = 21.00 (x at left z, DIAMETER) o100 sub (debug,8 x to [#_x_tmp + #_x_taper]) G1 F20 x[#_x_tmp + #_x_taper] G1 F7 z#_z_left x#_x_tmp G1 F48 z#_z_start x[#_x_tmp + #_x_taper] o100 endsub S250 M3 #_x_diff= [#_x_start_dia - #_x_end_dia] (is plus value, 11.3000) (debug,15 x_diff=#_x_diff) #_x_dec = [#_x_diff / 30.000] (so this s/b too) (debug,17 x_dec=#_x_dec) #_x_tmp = #_x_start_dia (init at 32.3) o200 while [#_x_tmp gt #_x_end_dia] (true till x is below end) #_x_tmp = [#_x_tmp - #_x_dec] (dec x_tmp by x_dec) o100 call o200 endwhile M5 M2 === Bug? Or one of my (in)famous typo's? Thanks guys. Ugly thought, if running in G7 mode, do I need to set the axis 0 max_limit to a diameter? It is currently stated in radius. 67mm's from centerline. Or 114mm diameter.

From the [AXIS 0] ini file: MIN_LIMIT = -2.5 MAX_LIMIT = 67.0 HOME_OFFSET = 67.783 Those are stated in radius. So the bring up procedure is to do an autohome without a tool mounted as the x will be zero'd left at switch open, which gives clearance even with a workpiece mounted, for it to go left and find the z switch which is about 57mm from hitting the chuck. And it parks about 25mm to the right of the switch. Since I had already cut the rust off the workpiece, I next drive the mounted tool so that it is sitting in gentle contact with the left end of that cut, touch-off z to 0.0, and measure the OD, in this case 32.3mm, and touch off x, redoing it if the DRO diameter isn't correct. The DRO diameter was showing 32.30. I think you might need to do some tool-changing, jogging about and switching between modes to see where you are (and also check the tool table entries).

Each holder is about $14 and I'd need another half a dozen, and the boring bar holder is $22 I'd need about half a dozen of those. My BIG bar is a 5/8 diameter that I made a clamp for, but that also leads to buying fitting more compound-slides as it can and has ripped threads out of the top, 10mm threads. I have been tempted to replace the compound with a steel square of the same height but haven't found my round tuit for tht job yet. Its (the OXA) about 10x more rigid that the alu versions that use the push button driven by a cam to lock a fixed V. The OXA moves the wedge up and down on a ramp on one side, much better grip.

Just wondering why you have such a large HOME_OFFSET, usually you only need enough to get off the switch unless you home like Andy and then you don't need any HOME_OFFSET.

On my CHNC I have an 8 station turret, I have many more tools than fits on the turret. I just keep the most used tools mounted and touched off on my turret. When I need a different one I load the tool in LCNC with TnM6G43 then proceed to touch off the Z to the face of my spindle (making sure that I touch off the tool table and I'm not in G54 so no offset is added) and the X to some material that I can cut a bit and measure the diameter then touch it off. I use tool 1 as my master tool and touch off the G54 Z offset with that. That shifts the Z for ALL the tools in the tool table. You can do the same with your OXA so long as you don't move the base. One advantage to using the tool table is you only have to touch off the Z in the G54 coordinate system to the material for one tool. Another advantage is you can specify the tool orientation and control point which is used by tool diameter offset.

Axis shows the result in inches, or millimeters, as selected by view mode, independently of the machine mode. But this is one of those days I shouldn't have chewed thru the straps to get up. Before I was anywhere near done, the backgear in the headstock started squawling someplace internally. I knew there was a bent shaft as that was obvious from the cyclic gear noises, but this was a dry bearing (or lack of a bearing) as it was just as noisy in neutral, so pumped about 2 cups of vactra thru it, made no effect on the noise, so I picked up the horn gave LMS some CC numbers for a new, complete, headstock, about $130 in an if it fits it ships USPS box. And so it will sit until that arrives, and I transfer the chuck, with the workpiece still mounted, to the new spindle, along with the timing belt pulley used for input. Roger said I should have it by Friday. The SDD arrived today, along with a new PSU, but that may wait till it crashes again as it has not crashed since I reformatted the drive installed the new hybride-binary image. They can sit on the shelf as spares till then. In the meantime, backups by amanda have been resumed, so I'll have the ability to recover to the state it was in at about 2:30 each morning. Tomorrow afternoon, Orkin will be here at 13:00 to see what sort of an insect infestation I have in the deck substructure give me a price to do that building like the house, with a full perimeter of protection. UNK if he can get to enough of it on the back ppty line though. Too much fencing, but they have a couple dogs I don't want to hurt. Thanks for the help.

I made my code a little starter, and put an RS274NGC_START_CODE line in the .ini, and it appears it is going to do, slowly, what I want it to do. Speed is limited by how much power I can get thru the timing belt to the spindle. Needs additional tension adjustment and bracing facilities but ALL that crap is directly below the spindle housing. A fix for that will be a cast iron bitch. Likely a lever bolted to the end of the shaft mount, projecting to the rear, where I might be able to rig a push screw against the outer end of it. The OEM motor mounbt was almost good enough for the 400 watt motor is came with, but swap it out for a 1 horse, and its way too puny. Too much flex. However, speaking of DRO's, there is not a tool velocity display in either the preview screen or the DRO screen, regardless of whether or not it is checked in the view pulldown. I would like to know if its following orders... So this is the first real, twasn't my stupidity, bug report on 2.6.8-pre1. Velocity doesn't show regardless of view selection. Heck, I might get this thing (a 2 speed polybelt drive for the mill) made yet. Replacing the 200 watt motor with the 400 watter from the lathe at the same time.

If your DRO is reading with 4 digits of precision your looking in inches, 3 digits of precision and your DRO is showing mm. If you always use mm then change your DRO to mm in the View menu.
