This might be doable with a programmed tool-change position at the cross over point between the two Z axes.

Re: [Emc-users] Toolchanges
On 25 March 2014 02:49, Gregg Eshelman g_ala...@yahoo.com wrote: rig isn't going to cut it. I've been thinking on how to build a tool changer for NMTB, without having to add a spindle encoder and fine motor control. Since the spindle has two drive lugs, probably an alignment jig that pinches from the sides on those blocks then something (solenoid or air cylinder) to hold the spindle brake. Here is a thought that I have had. You could have a small carousel of tools mounted on the end of the bed, so that at least two tool locations were within reach of the spindle. The carousel is unpowered, but has spring détentes. It can float vertically by a small amount. To pick up a tool the spindle plonks itself down on top of a tool, and rotates slowly, pushing down the carousel if the lugs are not aligned. When the lugs are aligned the carousel pops up, and triggers a switch. It is then safe to clamp the tool, and either lift the head (for a simple bucket-style carousel) or slide it out sideways. To change the tool the spindle puts the in-spindle tool into the empty slot, then coordinated movements of the table are used to rotate the carousel to place the required tool within reach of the spindle. It might be necessary to load some tools that are not actually wanted if the tool ordering is non-optimal. This is something of a hybrid between a rack changer and a carousel. The (only) advantage over a rack is that it takes up less space on the table. It could work with quite a large tool chain, for example. It doesn't necessarily have to be the spindle that moves the chain/carousel. there could be a pawl arrangement at the far corner of table movement. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.

The computer might affect speed, that rather depends on what step rate it can generate, and what step-rate you need. The F-word in the G-code only affects the linear axes, and the rotary axes either run at the speed required to arrive at the end-point at the same time, or if the rotary axis isn't fast enough to do that, then the linear axes will be slowed down so that they arrive at the end-point at the same time as the rotary. If you want to achieve constant cut-rate through the wood then you may need to generate G-code in inverse-time mode, (where you tell the system how long a move should take, not how fast to move). You will still have the slowest axis throttling the others, though. Normal feed-per-minute doesn't have much meaning in combined linear/rotary systems.

[Emc-users] Motion Mode in HAL
Does any HAL pin indicate if the current move is a G1, G2, G3 or G0 move? I am wondering if such a pin would be useful for things like laser cutters, which could cut with g1 and move with g0, almost automagically. I see some mention in the motion docs about free-tp-enable which indicates that the free planner is active.

I wasn't sure Florian was going to use a traditional controller and Hal for this. I think there is some confusion here still. The 7i39 needs three channels of PWM, one channel of PWM for each of the motor phases. It is a mainly-dumb drive with all commutation handled off-board in software. The Mesa three-phase-pwm is capable of providing 6 channels to drive every gate of the 3-phase bridge directly (with shoot-through prevention set by a parameter to the PWM generator) In the case of the 7i39 this is reduced to 3 channels to reduce pin usage and shoot-through inhibition is in hardware. I can't recall which scheme it uses to do this, whether it is 50%=0 or something else. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Start Your Social Network Today - Download eXo Platform Build your Enterprise Intranet with eXo Platform Software Java Based Open Source Intranet - Social, Extensible, Cloud Ready Get Started Now And Turn Your Intranet Into A Collaboration Platform http://p.sf.net/sfu/ExoPlatform ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

I also note that 99% of the inserts are through coolant, something I am not equipt to handle. It's a nice feature, and the coolant feeds in from the end of the holder thorugh a drilling.
