Yeah, I agree with Giarc. Looks like your router is chattering because of the lack of rigidity in the X axis. Rule of thumb is to never cut...
Kyle: What do you have your stepper motor microstepping set to? With a belt drive, you need at least 1/8 microsteps to get smooth movement....
Kyle: Impossible to tell from your picture what is happening. You need to send a picture with some recognizable shapes so we have something to...
I would wholeheartedly recommend upgrading your GRBL 0.8 to GRBL 1.1F. 0.8 is old and decrepit. I assume you are talking about the standard...
Hey George. GRBL has several release versions, all the way back to 0.7 and probably older. A lot of companies are still shipping preloaded...
Hey George The reason why you probably couldn't find anything on these problems is that no one has seen them before. I know in building over 50...
Personally, I like to use the Enable pin with the 6560's because this is what triggers the low current standby mode that keeps the motors locked...
Anthony: Do you know the part #? MG
I like the 6128 drivers. They are much newer design than the 8825's ir the 4988's.. Those dessigns are getting a bit long in the tooth. The...
For NEMA17's, I like the Panucatt Gradus M1 Pro board. You can use A4988's on it, but they also offer a bunch of more modern driver modules,...
By the way, you didn't mention initially that it was an A4988 driver. These are not optoisolated from the Arduino. Yet another reason not to use...
Is this a CNC machine or something else? I ask because an A4988 driver is not a real good choice for a NEMA23 driver for a CNC... MG
Hi Rob: It's potentially a blown output pin on your Arduino. Though it is pretty unlikely that the pin was blown by the stepper driver. Most...
NP. MG
What G-code sender program are you using? nothing you described sounds familiar... MG
Thanks for the kind words, Sharmstr. Unfortunately, I haven't had much experience with compression bits. It seems to me that you are going to...
I agree fully. The weak point in the OB Z axis is the 6 wheel setup. Just doesn't have the support needed for good stiffness. In my Ox HD...
I'm still not getting how this improves anything. Since, in either case, your cutting depth is limited to the length of the bit, that's as deep...
Rick: It's easy to add a second router mount to the Z axis to stiffen things up, particularly when you have a router with a long body like the...
Just take off the spoil board. That would give you another almost 60mm of travel. Your work would have to fit between the supports, and you may...
