    Where to find Imperial taps with metric shanks at a reasonable price?

    Well i bought a nice set of square key collets, M4 - M14 and that was the day i learned something new about taps and that is the variation in shank sizes. I have yet used a single one of them as none of taps i buy is correctly sized. Typically the mismatch is about 0.1mm (shank oversized, for...

    Best trick to adjust lathe serrated jaws quickly?

    All i have is a 4 position tool changer..:) With shims and all. Especially if boring is needed, the natural directionality is different and forces to remove even the main tool. Not great but acceptable for hobby use. I tested this method and it works wonders, it is enough just to have any tool...

    Best trick to adjust lathe serrated jaws quickly?

    Thanks for the answers, many ways to skin the cat it seems! Using the lathe tool with MDI as an indicator is intriguing, have to try that one out. This necessitates a tool with correct diameter which is not always the case though. Perhaps i could create some sort of stick protruding from...

    Best trick to adjust lathe serrated jaws quickly?

    Hi, I have been wondering how the professionals handle adjusting the CNC jaws which have serrated back edges for locking. There is no position indicators on my jaws and it often takes about 4 tries before they are in a correct spot when changing the diameters of stock. Do you have some sort of...

    New machine day - Brother S700X2 (UK install)

    You could easily route airblast or mist into 2 of these nozzles and only use 3 nozzles for cooling as 5 is overkill. I kept the left original arm and it provides sideways/backside coolant to the general area.

    New machine day - Brother S700X2 (UK install)

    If you get bored on adjusting those spray heads for different elevations, i made a fixed block with 5 nozzles on the backside of the spindle for myself, it was fantastic addition. It is for older brother machine though, might be different.

    Used Robodrill vs Brother

    When buying older models, the 3D paths might be slightly limited. For example i have TC-S2B-O and it supports only 3 axis simultaneous movement with 3+1 config. The additional axis is meant to be used for part flipping essentially and the Z axis limitation will affect the work holding principles...

    Issue Sending programs to an Older controller

    All of the cheap USB adapters kinda work, but if you want true RS-232 emulators you have to buy things like MOXA adapters which attempt to mimic all of the electronical behaviours that true hardware RS-232 port would have. These can connect to wireless or LAN ports too, so they are very flexible...

    Issue Sending programs to an Older controller

    My 20 year old Brother machine has some reserved program numbers and does similar thing if i attempt to DNC such values. IIRC they are values above 1999 or maybe it was 2999..This could be something similar? Try 1001 and 1005, does the situation change? This also wants to see Oxxxx at the...

    Macro Programming Fundamentals

    Right now i am not certain if you are simply attempting to reuse something from the manufacturer or trying to make your own. Your main program would consist mainly of "few" callouts (lets say its the program of measuring right front corners), which launch the probe into certain angular direction...

    Macro Programming Fundamentals

    I might suggest to work with rotating probe submacro. It will erase most of the repetition from the code (which is programming 101) and allows you to do modify or create new main routines rapidly. So what i have done is that the command is given to move toward certain angular direction from...

    Apologies in advance: TM-2P as a first CNC machine??

    Just to chime in on the probing, non-manufacturing quality wired 3D probes can be purchased for ~300$ and they repeat within 0.001mm if you use the same touch direction. It is complemented with a wired tool setter that is firmly fixed on your work table for about 100$. If the CNC software has...

    Form tapping M12 in 4140PH?

    Why not test it on another test article first? 10K spindle will tap M16 holes to structural steel, but probably not in 4140. You might possibly have to run it at higher RPM than suggested by calculators to obtain more torque from the motor. I have slapped regular tapping paste for M16 just to...

    Damaged BT30 spindle. grrr

    There is a lot of archived talk about side loads being dangerous with BT30 (likely in combination of pulling forces with angled flutes?). I have liked the performance of 1½ 90degree 4-insert shell mill on metal removal tasks for steel, but i have wondered if that is dangerous as its capabilities...

    A place to compile repair guides for CNC machines

    I suggest when you have spare time, take out the switching power supply and check out the internals visually. Capacitors most likely are starting to leak (or bulge) and it can lead to catastrophic damage (unrepairable) in the power supply.

    Macro Programming Fundamentals

    The machine has some calibration routines available and i use those values currently for corner probing. But the measuring is done bit differently on the calibration process so it most likely does not result in great accuracy when not doing it exactly same (except boss/circle center which does...

    Macro Programming Fundamentals

    Another head scratcher. If i remove tool length compensation with G49 or G43H0, this will result in the movement of Z axis towards the new position which is Z - Compensation! This crashed my probe in the safety block at the start of program as i had active compensation remaining from previous...

    LED lighting for inside an enclosure?

    I removed my Brothers ancient and corroded fluorescent tube housing and replaced it with a regular outlet (NOT inside the enclosure). This source has 110V output with safety isolation (= good), but almost all power supplies can operate within 110-240VAC so that is not a problem. It has dedicated...

    Macro Programming Fundamentals

    Thanks, i tried it again with refreshed mind and it works as supposed. There might have been some mix up with work offsets (where X Y was located). So the incremental moves are rotated just as the absolutes. I use this for boss/hole probing routine. This allowed to create very simple macro...
