Hi there.. I have the Ooznest version of the OX machine. Very happy with it. My questions arise around the CNC xPro v2 controller. I want to set up an easier way of setting the Z axis zero. I’ve noticed on the controller board there is an pin marked z-probe.. 1. Is this for setting the Z axis? 2. If so, how is this wired? 3. What code instructions need to be added/changed? 4. Does it in fact automatically set the Z axis zero? I assume that I’d then have to use the offset facilities to allow for the thickness of any gauge plate used. I also take it, that the offset can be used to set the X & Y axis zeros.. Set the machine to a specific/convenient location on the board knowing the exact distances to the relevant datum on the work piece. Sorry if I’ve no explained things very well. Thanks in advance for your comments and suggestions….
Th The probe is wired between GND and the Z-Probe screw terminal on the front of the XPRO, usually a crocodile clip on the endmill as probe, and the guage plate / corner finder on gnd) For usage, see Probing - Wiring Setup.and usage. · Issue #464 · grbl/grbl · GitHub (ie it doesnt set zero, you need to send G10 command to zero it) (You can accommodate the thickness / offset of probe diameter in your G10 command: set the current position where it stopped probing as the offset) You can probe X, Y and Z
This may help it is for the V2 board. CNC X Pro V3 Tool measurement z-axis Ignore the V3 in the link.
Sorry I understand this is an old conversation and apologize if the issue has been addressed already but I am new to CNC, just finished my machine, and can not get the z probe to work. I am using a xPro V3 with Estlcam controller, connected ground and probe inputs, and the card does not recognize when the circuit closes (plate probe touches plate), could some one help? Thanks in advance.
Hi Defender, Do you have one wire going to your endmill and another to the plate? A picture might help us, also make sure the input is setup in the estlcam settings. You can watch the state change on the setup page (small blue circles).. In the pic below its showing all the inputs triggered because it is not connected to any controller. You need to change the correct input to "Probe" and test it here first, just touching the plate to the "probe". might need to change the pull-up 5V setting. Gary
Thanks Gary, that is exactly how I have it: Input 1 changed to Probe in EstlCam, Connections: 1. Ground from xPro V3 to aluminum touch piece 2. Tool to probe pin of xPro V3 . Now, I noticed that by closing the loop, the blue light goes red at input 7, even if is that input is left unused, (my EstlCam only shows 7 inputs) The controller only shows input 1 as options, the rest other six inputs fron the controller are faded. It does not make much sense. Thanks a lot for your help
Once I disconnected everything, all back ON, changed input 7 to "probe", 1 to "unused", it showed a not faded input 7 in the controller screen and it triggers input 7 as it should when circuit closes. I wonder why it selects 7 vs. 1. Problem is solved, that what is important. Thanks for your help Gary!
It needs to be input 7 because it corresponds to the A5 pin on the arduino (from first page of CNC controller settings -Estlcam). Onputs 1-3 are for X,Y, and Z limit switches. I too tried to use the wrong pin and it stumped me for several days. Then when I realized why I wanted to slap myself. From the grbl wiki. The A5 pin is the probe which corresponds to Input 7 above.
Giarc, He's using an Xpro, but I agree the #7 is probably a carry-over from the Uno D3 is the probe on Xpro
Ciao qualcuno mi può aiutare a configurare z probe grazie Non riesco o fatto parecchi tentativi Non riesco a trovare in g code il comando z probe Uso estlcam con Arduino mega 2560
English please!: Google translate: Hi can anyone help me configure z probe thanks I fail or made several attempts I can't find the z probe command in g code Estlcam use with Arduino mega 2560 See EstlCAM's Youtube Channel and
or a plasma cut and with estlcam control and I would like to put a calibration of the z axis every start of the cut but I don't know the command in g code to do the z probe or connected the sensor and if I do the zeroing control axis it does it but I don't know which is ka line in g code axis probe
Can't help with EstlCAM, but in Grbl that would be G38.2 to probe, and G10 to rezero ( would assume they also follow standard Gcode conventions? ) If you go with a BlackBox and Grbl, you could refer to the video below, which uses a floating Z head, with touch off probing Watch from 33:35 for the Software section
or tried everything g28 g32 az g38 g38.2 nothing is wrong I don't know how to do it or even written to the software owner Christian but he doesn't answer
I am not sure how to get support from them as we are not affiliated in any way, but the Grbl ecosystem has a much larger userbase that makes finding help so much easier, so why not switch - Grbl-Mega will run on your 2560 gnea/grbl-Mega Do watch the video above
You need to setup the z probe under controller settings first, then reprogram the mega, after that the tool height or probe will work in estlcam you can even set a fixed location to do the probe, many options. Cheers Gary
Hello everybody could you recommend a cheap cnc card that works with openbuilds. and a very good reliable card maybe a proper card for openbuilds. thanks
grazie mille.una piu economica per fare delle prove ce? dopo sulla machina motero qusta del openbuilds
