First tried pattern 9 (Unipolar Half Step) because the scale was setup for that. the performance was the same. 20ipm max and would probably have to back that off... Second was pattern 10 (Bipolar Half Step) I know - not likely - and it wasn't. Didn't like it. Third was pattern 5 (Unipolar Full Step) I halved the axis scales also. similar performance.. 20ipm max. (and sound so far was pretty crappy) fourth was pattern 6 (Unipolar Full Step (two windings on)) Holy crap. That sounds nice. maxed out at 30ipm and didn't try any faster. Full stepping is .00054ish per step. Workable for sure. That is what the original control/software maxed out at. I will try faster when I get a chance. That is totally usable with linuxcnc - no mods to the control. I need to hook up the index and 100ppr and try some threading! One thing to try is - I think I can put the interface board back into step/dir and full step. I don't know what pattern it does though. sam (happy dancing..)

I found this http://www.maxton.com/ebay/emco/EMCO%20Compact%205PC%20Conversion%20to%20Mach3.pdf which talks about converting to mach. They remove the octal latch and jump through it. I wanted to see if I could get linuxcnc to drive the board without hacking the latch out. this is what I have found/figured out I think this is correct.. (this is with switch 1 on the interface board set to 'on' which puts the board into step/dir) x step pin 2 x dir pin 3 z step pin 4 z dir pin 5 index pin 12 estop pin 11 100 ppr sensor pin 10 74ls374 enable pin 14 74ls374 clock pin 1 I setup linuxcnc to send a pulse at every base period for the 'clock' that latched the outputs of the chip. (thanks Jeff E for the idea) this is using the 'reset' option of the printer port that allows for a cycle within each base period the same feature that makes 'double step' work. This allows me to 'latch' the 74ls374 each base period with the current step/dir pattern. It seems to work Now it took me a bit of tinkering to figure out that I didn't read the above article well enough to notice that you needed to set a switch to put the emco interface board into step/dir mode. During this time I was flipping bits on the printer port to try to figure out why it wasn't working. I think by default the interface is setup as phase drive. (4 phases per stepper) as I think I was flipping all 8 data bits on the printer port and was getting stepper clunking. Well - the performace of these drives/steppers are pretty poor. (assuming I have the timing right - and I didn't get too much time to play with it.) In the above article they talk about around 20ipm is about max. That is what I was seeing - plus there is a weird interaction when you run both axis at once. (they get quite a bit noisier for some reason). Now it could be that I don't quite have the timing correct - like maybe the step/dir needs to be inverted or or something - I will play with it more. I would also like to switch it back to non-step/dir mode. (phase drive maybe?) because there might be a reason the original software used it.. (better performance?) plus I think I have the original software and would like to try it out also.

That seems to be a delay caused by Axis, not by the interpreter. As far as the interpreter is concerned, there is no such thing as a load. (Or that was the case the last time I looked.) If you have some subroutines defined near the beginning of the file, there is a delay while they are noticed and skipped over. Otherwise, as soon as it reads a block it executes it. I could imagine a delay of 6-10 seconds, but not 6-10 minutes. My guess is that even when it sees the (AXIS, STOP) comment, it continues to interpret the file, it just skips the motion -- which in this case means it skips the graphics. There's a good chance that it even continues to interpret subroutine calls and loops. (Assuming I'm correct) I've never looked at the source to Axis, but it might be possible to change it so that when is sees the STOP, it starts reading the input directly and skips until it sees an (AXIS, START) or end of file.

Re: [Emc-users] emco compact 5pc lathe and linuxcnc (no mods to original control) (Now - hal is awesome)
So - as far as I can tell - the original control did 1/2 stepping up to about 19ipm - then full stepping from there to 30ipm. Now the lathe runs fine on full stepping from 0 to 40 (maybe 45)ipm. Half stepping only works well up to 20ipm-ish. (stalls above that) But why stop there.. I started thinking about if linuxcnc could do that (without coding anything) A couple advantages of halfstepping.. 1 higher resolution 0.000273403/step vs 0.000546806 per step 2 reduced resonance.. (I have not run into this with full stepping on the lathe) Then at normal cutting speeds - 16ipm you get a higher resolution. So why not have 2 stepgens running. One that half steps (type 9) with input scale of 3657.6073152 and the other full stepping (type 6) with a scale of 1828.8036576 (lathe calculation - metric screws) Then switch between the two stepgens at a specific feed (I picked 16ipm with a hysteresis of 1ipm) All I can say is - HAL IS AWESOME I setup a Lut5 with Jeff E's help (thanks jeff!) that switches the printer port between the 2 stepgens. A offset componant was used between the 2 stepgens to better align the phasing. (not tweeked 100% yet) but we jogged it around - could not tell that it was switching between the 2 stepgens and it always came back to 0. there is a bit more than that.. (ddt for calculating the axis velocity, abs of that, comp w/hystorisis, and stuff I have forgotten already.) And here is a halscope capture. Left side is halfstepping - right side is full stepping. The trigger is the velocity threshold. http://www.electronicsam.com/images/emco/Screenshot.png I think the offset could be tweaked more scientifically to maybe get rid of the blip.

Re: [Emc-users] query: how long was your longes G-Code program ever?
Maybe it's time to consider dropping the use of G-code and STL for additive manufacturing? Why not just go CAD to AMF? http://en.wikipedia.org/wiki/Additive_Manufacturing_File_Format And then just import AMF right into the interpreter and skip using G-code. The problem with having only one small nozzle (besides having only one small nozzle) is that it has to travel over the entire part. It's the same for only one laser using SLA so the G-code for motion is large and if the part has lots of on/off for deposition the G-code gets even larger. It works right now on 3-axis glue guns with only one or two nozzles and one or two materials. It gets further complicated if printheads or a micro-valve array is used since they might only have 25um nozzles and interlace hundreds or thousands of them with multiple materials.

(*) Obscure reference to the DVD format, and why it uses a collection of 1G VOB files instead of a single large video file. - DVD for video came out circa 1996. 1x speed DVD-ROM drives for computers hit the scene in 1997. Development work started some years earlier. Back then, the most popular hard drive size was a gigantic two gigabytes *unformatted capacity* and 16 *megabytes* of RAM was a mainstream amount though 32 megabytes was becoming popular as RAM hungry Windows 95 gained market share. By the time Windows 98SE was released, 256 megabytes was considered low end but 2 gig hard drives were still very popular due to being much less expensive than drives with larger capacity, like those monster sized 8 gig ones which tended to require special formatting software to trick creaky old BIOS code into working with them. DVD video has been stuck with the same limitations for 17+ years because to ensure every Digital Video Disc will work in every DVD player, no matter how old, it must stay with that old standard, in spite of all the anti-copying tricks the publishers try. Some of the latest attempts have somewhat busted compatibility with some players. The organization that oversees the standard is considering disallowing such discs to bear the official DVD logos and recommending a warning on them that they may not work in all players. P.S. My first hard drive was a *five megabyte* 5.25 full height MFM Tandon. After installing MS-DOS 2.2 and *all* of the software I owned (on 360K floppies) it was half full.
