Users are trying to use the touch plate to set XY0 in the lower right hand corner of their material. According to your gSender page, this should be possible. The page says: āProbing in any direction plus safe continuity detection ensures no broken cutting toolsā
I canāt see how this is possible since the code for the probe module seems to assume that the plate is in the lower left corner of the material. The bit moves left in X, then right until it touches, then left again and right to move to the Y determination position, then back until it touches, and so on. I see no way to change that except to edit the code.
However, since your page seems to say otherwise, can you please tell me what I am missing?
If I am not missing anything, and if this is not possible, I am suggesting this option for a future release of gSender.
@saskia Iāve done it with a macro that works fine. However, it does not verify that I have attached the magnet and that the touch plate circuit is good - as the gSender module does. So, carelessness or a bad wire leads to broken bits.
@gwilki perhaps the wording I used on the page made it muddy what the features were. I was just trying to say that whichever probing operation you select in gSender (whether itās XYZ, Z, XY, X, or Y) the continuity test ensures no broken bits.
As far as probing on other corners itās a feature that weāre working at for the future but isnāt yet complete. The plate in itās current form is just on the front-left, plus as you mentioned can leverage a macro if you want to run it on other corners but itās not as ideal. You can also probe in Z on other corners and then zero X and Y by eye. Still, not yet ideal
@chrismakesstuff Tks, Chris. Iāll close this thread, knowing that you guys are looking at it. This was never an issue for me, as I have never wanted to zero on any corner other than the front left. I also zero on the centre. I only started this thread because I saw others asking about it.
As you say, a simple macro will allow this and for any one needing this feature, the macro will work until gS has a better solution.
It would be nice for the probe menu to allow you to select which corner you want to probe instead of the default front left. This mostly comes up when I am performing two sided cuts, I always want to reference off the same corner, so when I flip the stock, the corner is no longer on the front left. I know I can work around this by flipping the axes temporarily in the firmware window, but thats more complicated than this needs to be, additionally, it runs the risk of forgetting to unflip the axes before you start a cut.
I agree it could be useful. I do probing from odd directions by enterring G38.2 commands via the console. BUT sometimes these commands appear to cause the jogging to run away afterwards!
@KalebMannion The subject of zeroing off of a corner other than the front left has come up before, and is likely being looked at by the Sienci gurus.
However, and you may be aware of this, on double sided projects, you do not change the XY0 position when you flip the material. So, you do not use the touch plate or the manual method to set XY0 for the second side. Only the Z0 changes. If you were to change, or reset the XY0, the two sides will not align.
@KalebMannion From what I have seen in videos from Vectric on two sided carving, Z Zero would be referenced from the top of the material (like lower left or whatever) for side one and side two would be referenced from the spoil board. The idea being you are referencing the same āFaceā of the material - assuming your material and spoil board are flat.
As @gwilki said, you would not have to reset XY0. I also think being able to reference other corners can be useful.
@stevendq Yeah, this mainly came up for me when I was cutting some drone winglets out of foam for work. I cut the stock roughly with an exacto knife and didnāt bother to measure it, so I could only ātrustā one corner of the work piece for referencing, and when flipping, that corner moves from the front left, to front right. So I could reference that corner for X & Y (by changing the X direction in the firmware settings) and use the spoil board for Z. Lined up pretty much perfectly.
@KalebMannion You may want to look at videos on Mark Lindsayās youtube channel on 2-sided projects. You use asymmetrical dowel pins to locate the piece when you flip it. It does not matter what the profile of material is that way. I do circles, triangles, etc. The dowels ensure that the top and bottom match every time.
@KalebMannion Youāre very welcome. The beauty of using locator pins is that you do not need to think about XY0 after the initial setting on the top side of the material. You drill holes in the waste area of your top side, then mirrored holes in your wasteboard. When you put dowels in the wasteboard holes and flip your piece, they have to line up with the holes you drilled on the top side. Your XY0 may well be off from the corner or edge of your material, but they will be spot on WRT to your top side carving.
This has been discussed before and, at present, the probe module in gSender only allows XY0 to be in the left front corner. I believe Sienci may be looking at making it possible to use other corners. In the meantime, itās quite simple to write a macro to use any of the other corners. If you are interested, DM me and we can go from there.
@fortis67 I have the macro written for the front right corner but will not have access to the PC that it is on until tuesday evening. If no one else has posted it, Iāll get back to you then.
I know that the AutoZero touchplate currently only finds XY from bottom left corner of the work piece but are there any plans to add the option to zero from any of the other three corners?
Hereās the reason why I would like to see that feature:
A project Iām working on in Vectric desktop has forced me to set the XY Datum Position to the bottom right hand corner for some of the pieces in order to mirror my cuts to other pieces and which have different dimensions to make the design clear enough to keep it straight in my mind. When I went to zero the bit for this piece is when I discovered that it doesnāt zero XY correctly from the bottom right corner.
I do realize that once I have completed my design in Vectric I can switch the XY Datum Position back to the bottom left, but my concern is that I may forget to do this if there are multiple iterations of design/carving.
Lastly, when using the AutoZero Touchplate to zero the bit, why does it it have to then move the router to the Zero position? When I tried to zero from the bottom right, after the probing was finished the bit was moved into the edge of the touchplate and then tried to go to the Z position with is much lower than the outside most edge of the beveled area of the touchplate . Luckily I didnāt break my bit or damage the touchplate. Wouldnāt it be better once the Zeroing process was complete to simply put the bit in the center of the AutoZero TouchPlate and then retract Z to a safe height above the touchplate? The user could then simply remove the touchplate and click on the āGoto XYZā button to put it to that position if they wanted (itās not actually necessary to start from the Zero XYZ position in order for your carve be successfull).
