Quick question please...not at my machine right now but have had an issue with it...self built based on open builds..using the black box and ob control it should be easy lol So my jogging on y and x are backwards for jogging only. once work home is set, its cuts correctly in the right directions etc. I have homing set with limits, currently set to front left (standing at the control end), homing works correctly also. Sorry hard ot explain, hopefully someone has run across this and its fresh lol My x and y axis are backwards. If i swap them in ob control they jog correctly, run a job and they are opposite. I just been dealing with the jogging being backwards lol. Not sure what to try..any pointers would be great..thank you ,mark
please do this: jog to the middle of the machine. setzero X and Y at this point (and Z if you like) select the serial console tab select the edit box at the bottom type in G21 G0 X100 Y100 now, where does the tool go to, relative to the 'workpiece'. confirming X is left/right and Y is forward/back thanks
What kind of machine is it? (for example a MiniMill or other moving bed style machine - can confuse you if you jog to "move the bed" instead of "jog to move the endmill relative to the workpiece" as you should)
Jogging to middle of machine entering the code asked..machine moveed to me(forward) and to the left Hello..thks for the response...jogging to center..zeroing out..the machine moves forward(towards me) and left
And if i jog the machine x+ goes left and x- right..opposite lol..same with y..y+ moves machine forward..control shows away from me.
This means your X and Y are reversed from what they should be, arrows below show positive movement directions. open OpenbuildsCONTROL connect to the controller select the 'GRBL settings' tab set 'step direction invert' as needed click 'save to firmware' at top left this will correct both machine movement AND the display
Thank you for all your help, pretty sure I have already covered that. (several times lol) changing the x and y values to opposite-- the jog is then correct. Ive made a simple square and circle for testing purposes, my screen will show the circle on the left and square on the right. OB control to run, I set working home to away from me (farthest away from me ) and right. Send code and machine cuts square on the left and circle on the right :0) .Ive had it for about a year and have cut a ton of stuff -- its just now starting to bug me lol So essentially the machine appears to cut correctly as it is , jogging is backwards. When setting up a new project in aspire, say 24 x 30--- have the two objects at bottom of page on the screen, when it cuts the cut ont he other end of the board than expected. Super sorry hard to explain. Mark
Ahh ok sorry missed it earlier, if you add an Attachment, there is an Insert Full image button next to it to add it to the post (bigger than a thumbnail) so as its gantry style, the jog directions as shown on the buttons should match Go to Grbl settings and make it Jog right first (jog is more important as a first step) X+ should move the XZ assembly toward the Right X- should move it Left Y- should bring the whole gantry Forward towards you Where you were standing in front of the machine taking the picture Y+ should send it to the back, away from you Z+ should raise the bit up and away from the bed Z- should lower the bit down toward the bed Once it jogs correct, save and restart. DO NOT change these again after, that is how it should be. Next, investigate the gcode (post here) and investigate your workflow That is, where is ZERO in your CAM (may be somewhere other than front left top of the stock) Where do you Zero out your machine prior to starting the job post the gcode and pictures of the cut on the machine cut some text if you can easier to diagnose than squares and circles that doesnt show which way they are
Super appreciate helping out, sorry about the thumb. I have the machine jogging correctly as stated, from standing as the picture shows. Actually think you got me on origin..I was set wrong. Now the only thing i see is the file cut correct position on piece if material, and displayed in aspire in the wanted position on the material...once added to OB control it appeared on the bottom..ill attach pics..hopefully the right way hopefully i explained in a way others can understand.

Your control screenshot shows zero off to the top, right of the drawing. Look at the Axes indicators, they show where Zero is. Your part is in quadrant-3 (all negative coordinates). The grid just scales around the drawing to help you judge its size You may just be confusing yourself by zeroing back-right. Use front-left like everyone else does
Re: "using front left like everyone else".....my electronics are 9n that end..the position of the table and surroundings say back right is where i need to be and all is fine .thanks for your help!
I assume you mean the homing switches. And yes thats fine and 100% correct (and best practice: see gnea/grbl) No what I am referring to is where you Set the Origin (in Vectric) and thus subsequently Zero out the machine (which is a manual action of the operator, and has no reliance on where the electronics is located) You as the operator has the choice of where to do these, as long as both are set in the same place physically, it all works (and yes, you can keep using back left if you wish) but as its a bit more advanced and non-standard it does create some confusion. As a beginner, starting off the standard ways helps you as things just look logically correct, and people help you faster when you do get stuck. As you build up skill, the more advanced features become useful (like purposely zeroing top-right on a piece where that's the best reference to work from, like a premade oddly shaped jewelry box for example, etc) If you start to play with other CAMs, the defaults are mostly front left too, so a good habit nonetheless. Watch the Hello world video for an overview of homing to XY-Max (which sets Machine Coordinates) and then Zeroing (which sets Work Coordinates) on the front-left of the stock. Its a widely used convention, and getting used to it will just help ease your learning curve as you get into more advanced work, probing, etc.
Yes sir I have homing switches-- have been running it for about a year-- had some downtime at the shop and decided to address the lingering problem-- so simple of me to not change the origin. Was good tho because I got to check over my whole machine :0) My electronics (black box, power supply and plug central (lol) is located right in front-- I dont want the dust and debris at that end if I can help it. I appreciate your rrsponses which led me to solving it, however 00 I have learned alone since day 1 so back right isnt "off standard for me" lol have a great week and thanks again Mark
