This is a link to some video of the problem to help try and pinpoint the issue
Any ideas?
I'm not 100% it is motor problem but I'll try anything.
Anyone seen anything like this before?

 

When you say lost steps those are because of a defect in the motor?
The current set up had same motors on both sides.
What kind of connection issue could cause it?
Thanks for info so far.

 

It does seem to be at the around the same place every time.

 

It does seem pretty square at extreme ends.
I’ll do some double checks tomorrow.

 

Ok time for an update.
A friend suggested I swapped the cables so Y cable 1 was in socket 2 and visa versa bad hey presto it seems to work fine. I’ve had it up to 3m/min with not skips.
Seems the build guy labelled them up wrong. Doh!
I’ve calibrated all axis and it seems to be working nicely.
Thanks to all here for you help.

 

Next questions
1. I’m using Universal Gcode sender classic 1.09. What is the best post processor to use with this software.
2. I’m using Aspire to draw the parts
3. The ox has the Makita router fitted. There seems to be limited collets available and I need to use 3mm / 4mm / 5mm and 6mm drills and cutters. I’ve not seen 3mm or 5mm collets for that router. Any ideas how I can hold the tools I need to use.
4. I tried an extension for er11 collets that I cut down but it doesn’t run true. When I use cutters straight into router then run lovely.
Any and all ideas or help appreciated.
Thanks

 

UGS does work fine it’s the right post processor I’m unsure about.
Does GRBL processor work best?

 

Hi,
I'm new in CNC world and need some help. I bought a workbee 1000x750 screw machine and it works great. Only issue is that it's not accuracy. If I design 260mm circle it comes out 261mm. Circle is perfect, not oval. I also cut maximum length Y-axis line whitch should be 770mm long and it came out 772mm long. Same thing in X-axis. 550mm is 552mm. I cut those lines manually using Universal Gcode Sender buttons.
For CAD and CAM I use Fusion 360 and post process general grbl.
Any Idea what's problem?

edit: I think I need to calibrate my machine

 

Have you calibrated your machine?

 

Thanks Joe! I think that's the solution. I miss that calibration part in Workbee manual or there's no mention of it. Maybe they include it next edition.

Hey Guys, anyone tried carving up some PurpleHeart on your OX before? This stuff is hard as a rock! I definitely went at it way too aggressive to start and had a nice little scare when the router took off in the wrong direction. Really had to slow things down and take it easy. I will be running some tests tomorrow to try and get some feeds and speeds dialed in, but was curious if anyone has any experience with this wood and has any advise for starting points.
Thanks!
Robert

 

Can't help you with feeds and speeds for cnc yet (still building my workbee) but routing purple heart I have found a high speed/medium feed best. It will go bright purple if it gets hot, but will fade back to browny-purple eventually. Watch out for the grain direction - it tends to tear out sometimes. Also blunts tools quickly. Does take a lovely finish though.

Hi I'm trying to decide on the Makita or Dewalt router for my Ooznest OX. My first thought was the Dewalt, but I will be cutting acrylic and PVC as well as wood. But I'm thinking the lower rpm of the makita would be better for the plastics. Any advice would be appreciated. Also would I need the mount adapter to mount the Makita in the Ooznest mount kit?

 

Hi Lee,

I use a Makita trimmer/router CX range with adjustable speed and custom mount and it’s great for plastics. Trial and error will get you the best feed and speed rates with the type of material used. I haven’t ever used a dewalt router so can’t give you an option. Good luck, Rick.

 

You'll need to check with Oozenest, but they seem to have discontinued the Ox - it's no longer on their website. If you buy the Makita from Oozenest they supply a collar to fit the Makita to their standard router mount. Otherwise there are adapters available on Thingiverse for 3D printing. If you haven't got a printer I am sure someone on here could help you out for the postage cost. (including me if you are UK based) If you are cutting plastic a lower speed is a definite advantage, although lots of people on here will tell you that they are cutting plastic with the Dewalt. I cut some polystyrene this afternoon with the Makita at its lowest setting and would have gone slower if I could.
Alex.

 

@ Ryan Lock I decided on the Makita Router and my order from you for OX router mount, Makita adapter and a couple of collets has just arrived. The mount kit came with 6x 20mm M5 low profile bolts. I can only figure out where 4 of them are used, what are the other 2 for?

Also are the downloadable files for the OX still available? Even though you no longer sell the OX it would be nice if your website had a section for discontinued models.

I got my new router mounted and trammed, went to try it out, but my workshop PC is dead. I'm gutted I can't try it out this weekend and am gonna have to source a new motherboard on Monday.

 

Hi,
I am a happy owner of ooznest CNC 1500x1500 screw drive with Dewalt D26200 as spindle.
I am urgently in need to perform heavy drilling operation in plywood, around 500 holes, 8mm diameter. Holes have to be made before cutting out elements as preferably I want to make all the other operations (pocketing, profiling) using the machine.
I have already ruined one router bit and burned the holes (they are practically black).

Dear users,
what is the optimal (regarding costs, speed and bit usage) way to do drilling operation ? I am using Vcarve Pro for preparing models and generating toolpaths.
Thank you very much for your help!
